Yeah, that *IS* the correct way to get at the WindowRecord of a window. I think 
the correct way to typecast is:

	var windRec:WindowRecord;

begin
	...
	windRec:=WindowPeek(yourWindowPtr);
	...
end;

You could also pass a pointer to the window's record when it gets created using 
(Get)NewWindow and setting the wStorage parameter to your window record.
The Window Manager function FrontWindow will return the currently active window
(i.e. if myWindow=FrontWindow then ...).
