A couple of things: 1. You’re keeping the panel window instance reference in InspectorWindowController.sharedInstance, but not keeping a reference to its window controller. That causes its window controller to be deallocated early, although that likely has nothing to with the rest of the problem, since the panel doesn’t have any custom behavior yet. You should keep a reference to the window controller instead, and that will keep the panel alive too. 2. You’re doing a “performClose” to hide the panel. If you do an orderOut instead, you get the behavior you want. Note that you are getting a new instance of the panel because the window segue mechanism decides the first one has disappeared. Again because it’s not documented how window segues work, there’s no way of knowing what the “correct” behavior is supposed to be. (Your panel window is correctly set to “Single” mode in the storyboard, which is what’s supposed to prevent multiple instances from appearing.) Also undocumented — forever AFAIK although others on this list may know more about this — is what a window “close” (or “performClose”) does, other than ordering out the window and (if it’s set to release on close) to release it. Whatever a “close” actually does, it’s making the storyboard mechanism unable to find the panel instance, so it creates a new one. (Your panel is *not* set to release on close, and I was able to verify that it’s not being released regardless, so this is not anything you appear to be doing wrong.) _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
