Handle GetDIHandle(i)Integer i;{
	short theType;
	Handle theHandle;
	Rect theRect;

	GetDItem(thePort, i, &theType, &theHandle, &theRect);
	return theHandle;
}

DialogPtr gMesgDia;

BeginMessage(){
	GrafPtr savePort;

	GetPort(&savePort);
	if(NIL == (gMesgDia = GetNewDialog(resID, NIL, (WindowPtr) -1L))){
		return;
	}
	SetPort(gMesgDia);
	SetIText(GetDIHandle(textITEM), (StringPtr) "\pYour message here.");
	ShowWindow(thePort);
	DrawDialog(thePort);
	SetPort(savePort);
}

EndMessage(){
	if(NIL != gMesgDia){
		DisposDialog(gMesgDia);
		gMesgDia = NIL;
	}
}


Now, just say:
BeginMessage();
... do your work ...
EndMessage();

You might also look at your event loop, and see if you are calling
isDialogEvent() and DialogSelect() there.  You should be. See Inside Mac
for more info on those two calls.
