Hi all, I am using PSMTabBarControl in a project, but it is giving me some headaches. When I remove a tab (actually, any tab but the rightmost) from the NSTabView it is controlling, I get this error: 2007-12-18 13:48:45.753 MyApp[743:10b] *** Collection <NSCFArray: 0x13a0e0> was mutated while being enumerated. In the demo project that comes with PSMTabBarControl, this error does not occur when removing any tab. Yet I know this error occurs when I remove a tab (which is not the rightmost tab) because when I execute the following: Code: NSLog(@"will remove tab"); [tabView removeTabViewItem:tabViewItem]; NSLog(@"did remove tab"); "did remove tab" is never printed. Any thoughts? Thanks.
