Fixed bug #458 ------- Comment #7 From Christian Walther 2007-07-23 01:10:30 [reply] ------- Fix for some Cocoa memory management problems. OK, I think I've nailed the memory management problems with the attached patch. Too late for the release, but oh well. It shows that I haven't done much Cocoa lately... took me a while to figure out that NSWindows don't retain their delegate.
