Rogier,
You should only call FrmDispatchEvent if none of the other event
handlers (system, menu, application, etc.) handled the event: e.g.,
do {
EvtGetEvent(&event, evtWaitForever);
if (!SysHandleEvent(&event))
if (!MenuHandleEvent(NULL, &event, &error))
if (!AppHandleEvent(&event))
FrmDispatchEvent(&event);
} while (event.eType != appStopEvent);
In your example a frmLoadEvent will load the form but then call
FrmDispatchEvent(frmLoadEvent), which is something you don't want
to do.

Daniel.
