Hi !


I've got a problem:

My my program uses setitimer() with ITIMER_REAL to call an interrupt-routine
via SIG_ALRM (this routine does a refresh of some graphics on the screen).

With DOS 6.22/7.0 everything works great. But my program crashes when run under
Win95 in a DOSbox.

It crashes right after it received a keypress-event with GrMouseGetEvent()
regardless if that event will be processed or not.

I've looked in the DJGPP-FAQ and GRX doc but I couldn't find a clue. 


Can somebody help ?


greetings,
hajo
