I am testing a small DJGPP/GRX program that initializes graphics and draws a line. The program works fine, except when I load the Carroll Touch (carrolltouch.com) touch screen drivers ( tapi.exe, ctkern.exe, ctmouse.exe) The touch screen mouse works fine alone too.

But GRX fails in GrSetMode( ) when the driver is loaded, and the computer hangs. The mouse driver uses COM 2 - S/W Int 55h, 56h - H/W Int 7 - I/O address 300.

Does any one know of a conflict or what might be in conflict with the GRX?

I don't know, but it can be that the mouse driver is confussed if you set a video mode other than the standard vga, try to set GRX20DRV with "stdvga" and call GrSetMode with GR_default_graphics.
