The motivation for using a panel was to avoid the window from becoming main (so key equivalents would be sent to the document window, if not handled by the HTML output window). Unfortunately window ordering ignores non-main windows when a window is closed meaning that bringing up the Find dialog from an HTML output window and then closing it, would bring the current main window to front, eclipsing the HTML output window.
There are places where we iterate through the delegates of NSApp’s ordered windows. Since the window may stay around longer than it’s (NSWindowController) delegate, we should be sure to set NSWindow’s delegate property to nil.
We now explicitly disable it for targets that hasn’t yet been upgraded to ARC. This way, it’s easier to get an overview of which targets hasn’t yet been upgraded and ensures new targets has ARC enabled.
