[AD] Hardware mouse not displayed in Windows

[Evert Glebbeek <eglebbk@xxxxxxxxxx>]

The attached patch fixes a problem in Windows where the hardware mouse 
cursor wasn't displayed until it was moved.
Apparently, Windows refuses to redraw the mouse cursor unless the mouse was 
moved, so I've faked a mouse movement event.
