There are always going to be race conditions like this — the user can always press a button at exactly the same time something asynchronously makes the button meaningless. Your code just has to deal with it safely. Presumably something underneath will return a kSessionClosedError, and the UI code will just ignore it because the sheet’s gone already. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
