I can't get the cursor to blink in a dialog box.  All my previous dialog
boxes have been handled by "ModalDialog()" which does all the right things
for me.  Inside Mac tells me that I need to call "IsDialogEvent" and then
"DialogSelect" after a "GetNextEvent" even if "GetNextEvent" returns false
in order for the TextEdit cursor in my modeless dialog box to blink.  I
translated that statement to this code:

    if (GetNextEvent(everyEvent, &anEvent))
	/*
	** This is my event handler, it also calls IsDialogEvent and
	** DialogSelect
	*/
	handle_event(&anEvent);
    else {
#ifdef THISDOESNTWORK
	if (IsDialogEvent(&anEvent))
	    DialogSelect(&anEvent, &theItem, &theDialog);
#else
	/*
	** This also doesn't work, but I tried it because a different
	** interpretation of IM indicates this would be correct.
	*/
	(void) IsDialogEvent(&anEvent)
	DialogSelect(&anEvent, &theItem, &theDialog);
#endif
    }

The above code is from memory so don't tell me that my arguments to
DialogSelect are in the wrong order.  I've already spent a while bashing
my brains against the wall looking for little things like that.
(Well, now that I've mentioned it, doubt fills my brain, "Did you REALLY
make sure ??? :-)
