Since you are explicitly making your window key, it your subclass should be having sendEvent called. Of course, there are some key equivalent checks that occur before the event is routed to the window. This is why key assignments on the buttons should work without you getting a sendEvent. If you put a NSTextField in your panel, can you type in it? -raleigh _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
