Aye.. Ive done that. Ive defined update to just call paint and paint write
everything to the
background image then does copies it to the display. But the sprites still
seem to occasionally flicker...
Each sprite holds 32 images for the animated sprite at various angles and
the flicker seems to occur
when I switch to display a different image . <shrug> maybe Im just imagining
it.
