I am using grx with DJGPP.

I am having a problem in one function. By remming ot sections of code I have isolated the problem down to GrMouseGetEventT( GR_M_EVENT, &rat, 0 );

In Windows 95 I get fairly predictable results but in DOS I lock up, hard enough that ctrl+alt+del does not work, I have to use the reset button.

In DOS if I single step through the function (and function calls with in my function) my function works as expected, I guess the debugger is getting in the way.

If I erase the mouse pointer with GrMouseEraseCursor(); then, other than having no mouse displayed, my function works as expected from both DOS and Windows.

Any ideas? (What did I do/not do?)
