a bug on  winXP.
leaves alot of droppings on exit, on the window beneath it.

seems to occur upto several 100's of a second after window is shut.

i tried adding  Sleep(1500); Redraw(the_desktop);  code at the bottom of 
 dxwindow.c  but it still occurred, seems to happen after the end of 
main().

i added the sleep, as i thought it was a timing issue, it still trying 
to draw after the window had gone.
but whatever it is that draws to the window, doesn't check if the win32 
window handle is still valid.
