Thank you Gillmer.  This worked just great! :>  I still have to play around
with the MediaTracker, but I got it to load and dynamically resize
(something I had to code hoops around in VB! :>).

I've been hearing things about doing things with a double buffer instead of
in memory, or objects that are directly being used to display on the screen.
Could you point me in the right direction to start finding information on?
Much appreciated.

Thanks again! :>
