Updated drivers can be found on your graphic card manufacturer's website.

To identify your graphics card, open the Windows Control Panel, and choose the 'Display Properties' item. In the dialog box that appears, click the 'Settings' tab (normally the right-most tab). At the bottom right corner of the Settings pane is a button labelled 'Advanced...'; click this to open another dialog box.

In the Advanced box is a tab called 'Adapter', click this and information about your graphics card will be displayed. The important pieces of information are the Manufacturer and the Chipset. Common manufacturers are Intel, ATI, Matrox and nVidia. The chipset number or name will be useful for finding drivers on the manufacturer's website. (The model name is sometimes also displayed as the first line in the Adapter tab).

The safest way to find drivers is to search for the manufacturer's website (some are listed below), and then look for a 'downloads', 'drivers' or 'support' section of the site. Depending on the site you can then search based on your graphics card's model number and download the driver files. The manufacturer's site should include instruction on how to install the files - normally the download is simply an installer you can run.

Ati: http://www.ati.com/support/driver.html
nVidia: http://www.nvidia.com/content/drivers/drivers.asp
Matrox: http://www.matrox.com/mga/support/drivers/latest/home.cfm

On older Windows platforms (Win NT v4 and Win98) that do not have a Unicode Arial font installed some symbols (for instance, those in the Properties pane) will not be displayed correctly. To fix this problem you must install a Unicode Arial font on your system.

For some users of MacOS X 10.2, 10.3 and 10.4, the cursor graphic may randomly display a white background instead of a transparent background. This does not affect the overall use of the program in any way, and a fix for this is planned.

We have now produced a correct replacement file. You can download this file from here. Please copy this over the old file in your installed software, which by default is installed at: C:\Program Files\Crocodile Clips\Crocodile Physics 504\product\Examples\Motion & Forces\Motion\Newton's laws\. Once the file is replaced when the software is run again the correct file should appear when you click on the 'Newton's third law of motion' example.

We have identified the following problem with Crocodile Physics v401 whereby under certain circumstances, users may find that pressing the fit button whilst drawing a graph causes the software to crash. This problem will only occur when:

- The data currently collected does not fit on the graph and
- The graph is selected so its control pane is visible, then
- A part in the simulation is selected and (whilst its still selected) the fit button is pressed

To avoid this happening simply click anywhere in the graph window before pressing the fit button.

So any files saved in version 410 in which you have saved custom parts into the parts tree will crash when you try to open them in version 504. We are looking into coming up with a long term solution for this but in the meantime if you have any problem 410 files which won't open in 504 then please send them to us and we will recover them for you.

If you receive either of the following error messages during installation, please reinstall using an organisation name of less than 20 characters:

Unhandled Exception
Error Number 0x80040707
Description Dll function call crashed: LIC32.GetLicenceSite
Setup will now terminate.

or

An error occurred while launching the setup. (0x80040707)

On Macintosh:

Some users may experience problems using Crocodile Technology on Macintosh G3s running OS 10.2. If you experience any difficulties please contact us with details.

The automatic link between Crocodile Technology and real-PCB may not work if you are using a computer account which has restricted permissions. However, there is an alternative way to transfer from Crocodile Technology to real-PCB for cases when the automatic link is not feasible, in Crocodile Technology you can choose to save the real-PCB netlist and then use the import function in real-PCB to open it.

If you are using an old version of Windows and have difficulties installing real-PCB your Microsoft installer service may be out of date. For Windows 98 or ME you can update your files by using the utility instmsia.exe available to download from microsoft:

For later operating systems follow the links in the above webpage.

After running this update restart your computer and then install real-PCB.

Unfortunately we have found a defect in the 'Server Installation' route on real-PCB CDs sent out before January 2005. This has now been fixed so if you received your real-PCB CD before January 2005 to gain access to the new server installer please email support@crocodile-clips.com with your name, your school's name and address and your real-PCB installation serial number from the back of the software case..

Currently it is not possible to run real-PCB from a network drive (i.e. UNC shared folder). This is because real-PCB requires certain registry settings on the client in order for it to run properly. If you do use this method, real-PCB will start up in demo mode. For any further information please email support@crocodile-clips.com.

On your computer go to Start > Settings > Control Panel > Display and select the Appearance Tab. Then under Colour Scheme select the 'Default (Blue)' option..

When using the trig axes in the graph part, some users find that panning or zooming the axes causes the increments of 90 to change to increments of 100 - unsuitable for trig work.
To avoid this, switch automatic divisions off before you start panning or zooming (in the Axes tab of the graph part side pane).

Under certain circumstances use of the text box in Crocodile Mathematics v401 can cause the programme to freeze. Risk of this occurring can be minimised by avoiding circumstances where the text box scroll bar appears. To these ends, it is best to enlarge the text box (using the circular points on its frame) before the amount of text you are typing 'overflows' causing the scroll bar to appear.

Manipulating a text box in a file saved in a previous version of Crocodile Mathematics may cause the application to freeze. Solution: Open the file in Crocodile Mathematics 1.3 (or the version in which you first saved the file). Enlarge the text box so that it contains plenty of extra room. Save the file. Opening the file and manipulating the text box in Crocodile Mathematics v401 should no longer cause a freeze.

Font type and size may be reported wrongly. Fonts and text size can be changed and saved, but the state of text may not be correctly reported in the text box control pane. This should not cause a crash.

Text may flow outwith the text box. This can happen for a number of reasons including use of a mouse scroll wheel while the text box is selected. Under these circumstances the application may freeze. It is recommended that in the event of text appearing outside the text box you immediately use the main application scroll bar, on the right hand side of the Crocodile Mathematics window, to position the text box more centrally in the mathspace. Then deselect the text box (by clicking away from it).

You will need to install an appropriate language library.

PC: Win 98,ME,2000

Go to Control Panel->Regional Options. Under the General tab, in the 'Language Settings for the System' section, check any language that is composed of non-European characters. Click OK to install these libraries.(You made need your original Windows installation CDs.)

PC: Win XP

Go to Control Panel->Regional and Language Options. Click on the Language tab to view the contents of the Language pane. Tick the 'Install files for East Asian languages' option. If necessary, confirm that you wish to install these added files and then click OK.

Internal angles can be read, but not set through connections.
Examples: If, therefore, a number part is connected up to an internal angle, the number can only report the value of the angle: the number part itself cannot alter (i.e. 'set') the internal angle. Likewise, if you connect an internal angle of shape 1 to the orientation of shape 2, a change to the internal angle will alter the orientation of shape 2. You will not, however be able to alter (i.e. 'set') the internal angle by altering the orientation of shape 2.

This behaviour is reflected by the uni-directional arrows representing such connections.

If this is the problem you are having then the only solution at present is to upgrade to IE5.5 or above on any machine you wish to print our courseware from. Please find a link to Microsoft's free upgrade to IE6 below: http://www.microsoft.com/windows/ie/downloads/critical/ie6sp1/default.asp
