Avoid setting the value if it's the same as the current one. Sometimes the bitmap was drawn at the wrong position. BTW looks like sometimes the event mask set with SetMouseEventMask() isn't resetted when a MouseUp occurs. In fact, sometimes when I click on the window decorator (in Backgrounds), I still get MouseUp/Down event for the ColorControl
