I'm sorry, but you are fixing symptoms and not the problem. Calling the repaint is correct, otherwise we might end with artefacts. The problem must be that another effect is still holding a reference to the window and thus it's being shown again. Try disabling the fade effect or any other closing animation effect you might be using.
