Thanks Jens. On the other hand now runModalForWindow increases retainCount! Why is that? > It makes no sense to me. > > > It’s probably being retained and then autoreleased by AppKit.

But the retainCount is needed for successful release of the window, right? I allocate the window and then deallocate it when I'm finished with it. But runModalForWindow increases retainCount to 2, so when I release it, it's actually not destroyed and causes a crash afterward, because for some crazy reason the OS tries to repaint the view in it, despite the window is already closed... > > > Also the window still appears in background (code below) and cursor cannot > be changed. > > > What app is this in?

But the app/plugin is all C++, so there should just be a small layer, that does what Carbon does normally... ugly world of development for Apple... > NSUInteger style = NSBorderlessWindowMask; > > > Borderless windows can’t get keyboard focus by default.

I don't know much about Objective C, how should the MStringToNSString be implemented to create the autoreleased NSString? (sorry for lack of knowledge, but I just don't plan any further development in objc, just want the small layer...)
