There are only two events that are of interest in this loop. The
pressing of the ESC key, which is checked and the open form event
which I am trying to pass on to the form handler.

That is not the problem. I was trying to simplify this to the least
amount of code, to keep it simple. This is the actual routine and it
does have SysHandleEvent and MenuHandleEvent. I have tried it both
ways without success.
void CheckUserPaused(void) {
EventType event;
UInt16 err;
EvtGetEvent(&event, 0);
if(event.data.ctlEnter.controlID == btnESC) {
progPaused = TRUE;
}
else {
if (!SysHandleEvent(&event) && !MenuHandleEvent(0, &event,
&err))
FrmDispatchEvent(&event);
}
}
}
