That's my guess also. And no, the controller IS releasing the window, it only has the standard private hold to it, and nothing retains it. Otherwise it should show up in Leaks (and it doesn't). 

My conclusion is that AppKit must be calling -updateTrackingRects /after/ the window was closed. IMHO that's a bug.
