The window of "Colors!" suffers bad artifacts when a color is chosen, especially when the app is open in front of other windows

[Giova84]

The described issue doesn't always occurs; sometimes the window of colors is minimized/hide (IIRC the BeOS version act in this way, which IMHO is the best behaviour, since it doesn't interfere with the screen, so you are able choose a color everywhere on the screen), sometimes becomes a completely blank window, sometimes is drawed with artifacts and sometimes doesn't disappear at all without artifacts, but the mouse pointer will be "printed" on his window: all these behaviour happen when the color chooser is clicked.

I noticed this behaviour since its first releases; currently I compiled "Colors!" from the last available source here.
