I did called IsDialogEvent regardless the return value of WaitNextEvent
or SystemTask/GetNextEvent.

One more strange thing, when I tryed to check the event return
from WaitNextEvent, I never found a nullEvent(I have a break in the
program when a nullEvent is found) What happened?

System : MacClassic, THINK pascal 3.0.1
