There are plenty of ways to write refcounting bugs. But the refcounting bug is just a theory. All we know for sure is that something is disabling the menu items. I assume you have not turned off the default autoenablesItems property on the menu, so that leaves a few possibilities: 1. The target of your menu items is being replaced with an object that does not respond to -menuClick:. 2. The target of your menu items is being deallocated, and a new object is being allocated in its place that does not respond to -menuClick:. 3. The target of your menu items is being deallocated, and NSMenuItem’s weak target pointer is being nilled out (special case of #1). 4. The menu has a delegate, and it implements of one of the menu update callbacks to disable the menu items. 5. Some arbitrary object in your app is grabbing a reference to the menu items and disabling them. --Kyle Sluder > > -- > Best regards, > Andreas Falkenhahn mailto:andr...@falkenhahn.com > _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
