Well, the object graphics are suppose to *be* a Z-buffer,
so I wouldn't know how to do this off-hand.

Since you think it is a graphics card issue, have you
tried doing your window rendering in software, rather than
hardware? Set the RENDERER keyword equal to 1 on your
WIDGET_DRAW call.

Cheers,

David
