Ive been testing a program which uses the GetPixels function (I think that is what it is called) which returns as part of an array the colour of the pixel that has been clicked with the mouse. This works in Windows 98 (Riva TNT) and on a Windows NT pc. I tried it on another NT machine but it always crashes at this point with an error message similar to “cannot access memory xxxxxxxx”.
Sorry to be so vague but would this be a graphics card problem or a windows NT problem?
Im not sure what the graphics card is in the NT machine that crashes.
Thanks
