hi vince,
my windows are NSBackingStoreBuffered
is that what you mean by background property? i am just using a subclassed
NSView & a CGContext for drawing
this is a very generic use of cocoa windows, i can't figure out what is
wrong
i noticed that if i show/hide a window it will stop working altogether --
can't resize it, etc.
thanks,
bill
