Another solution would be to simply set the BackStyle of the UserControl to Transparant, since the mouse move event will not be fired while the mouse is over a transparent part.
Apparently, if you set the BackStyle to transparent... none of the components in it are visible (similar as if the usercontrol was invisible). Is there anything else that needed to be set to avoid this??
