Of course not!! But it at least makes the application available for the time
being (needed to be urgently fixed or at least worked around).

I have posted the methods and ivars I have added to my subclasses. I can't see
any obvious conflict with Apples API modifications!? And the app crashes in
setWindow!? I see it that way. Apples implementation of NSScrollView::setWindow
looks probably similar to this:
- (void)setWindow:(NSWindow *)window
{
// remove observer for _window::contentLayoutRect
[_window release];
_window = [window retain];
...
// add observer for _window::contentLayoutRect
}
Do you agree?
I expect a bug in Apples code where the ... are. May be a return before adding
the observer again!??
I can only hope Apple fixes this with a Software Update soon!? Or do you have
any further hints what I could have done wrong? Here are my ivars once again:
@interface GSScrollView : NSScrollView
{
NSSize _minSize;
}
@interface GSWindow : NSWindow
{
BOOL _suppressBecomingMainWin;
GSWindow *mainWin;
id filesOwner;
NSRect _tempRect;
}
Thanks,
Andreas
