Don't pay attention to retain counts. They rarely indicate anything useful. For instance, in your first case, how do you know that the menu hasn't autoreleased the submenu? -autorelease does not decrement the retain count, but promises release later on. Check after the runloop has run--you may see different results. As far as crashing when removing a menu with a submenu, that shouldn't happen. Chances are, it is your code that is causing the crash (I say this from personal experience). Otherwise it is one nasty bug. Keary Suska Esoteritech, Inc.
