Re: trackmouse problems in Leopard

For a quick test, see if putting in the following in your cell 
subclass makes it work again:

- (NSUInteger)hitTestForEvent:(NSEvent *)event inRect:
(NSRect)cellFrame ofView:(NSView*)controlView
{
   return NSCellHitContentArea | NSCellHitEditableTextArea | 
NSCellHitTrackableArea;
}

It might not be exactly what you want, but I'm pretty sure your 
solution is a good implementation of this method.
