	Here is portion of the code that I use in my SigmaEdit DA (written in
LSC) for getting the event.  I have no problems as you will see:
DoEvent ()
{
	BlockMove (*((long *) & myParam->csParam[0]), &evtInfo.event, sizeof (EventRecord));

	switch (evtInfo.event.what)
	{
		case mouseDown: 
			DoClick ();
			break;
		case keyDown: 
		case autoKey: 
			DoKeyDown ();
			break;
		case updateEvt: 
			DoUpdate ();
			break;
		case activateEvt: 
			DoActivate ();
			break;
	}
}
	Hope this helps....
