It's not a problem caused by Windows XP as such. It's the video card and video drivers, and the problematic video cards started shipping around the same time as Windows XP. They run InstantTrack fine in full screen mode, but can't show the graphics modes used by InstantTrack in a window.

Some such problems can be avoided by running InstantTrack in VGA mode. This can be done by setting vga_resolution = 2 in the IT.INI configuration file.

A good way to work around the incompatibility is to run InstantTrack inside an emulation environment that knows how to deal with modern video hardware. DOSBox is free and works for this purpose.

This is covered to some extent in the InstantTrack FAQ at http://www.amsat.org/amsat/intro/itfaq.html

Hi Ron,

On my WinXP system, the default DOS properties had memory set to to 512K. This leads to ridiculus error messages like "insufficient memory" to run the IT map when the system has 1 gigabyte!

To fix this, left-click your DOS Wizard icon and select the "memory" tab. Set eveything to AUTO and set "protected" and "HMA" and you should be all set. This set of options is perfectly fine for just about any DOS application. I suspect MS set the options this way just to make it a pain in the neck to run DOS programs as all the previous versions of windows that I have seen defaulted to AUTO.
