If you experience any display issues using our software on Windows NT it may help to install service pack 6 and update your graphics drivers.
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.
