- MyDocument.xib produced a crash wehn decoding where the NSSplitView is observing it's children, particularly the WebView. Fixed by rebuilding the xib. - Conversion to ARC created a cycle between EditPaneTextView and it's EditPaneLayoutManager instance variable; fix with a weak references, which requires targeting 10.7. - MyDocument had a cyle with it's NSTimer; this most likely was a leak under GC also, as the timer would pin the document in memory beyond the window close. - removeObserver: was being called on NSUserDefaultsController, which isn't a valid selector; most likely the NSTimer leak was preventing this from causing a crash. Replace with removing specific KVO observers.
