Hi !!

I would like to move the icon of a ball around the client area of
a window.

Using the WM_TIMER event I can compute the new position of the icon,
do an InvalidateRect() of the client area and send a WM_PAINT message
to the window to get the DrawIcon() done. Ok - works fine ....

The only trouble is that the icon tends to flash, so the movement isnt
smooth. I know that I should probably only InvalidateRect() the part
of the client area that will need redrawing, but..

Any other ideas on how to get this done *NEATLY* ? So all you
animation freaks and game writers - ideas please !
