Yay! The fix works fine. Thanks, Steve. Quick work of it.
If you've got the latest version I just uploaded Bert, you've also got the $COLOR32 keyword now. Give it a try sometime and see how it performs for you also. It should be as simple as:
$COLOR32
SCREEN _NEWIMAGE(640,480,32)
Line (100,100)-(200,200),Red,BF
Circle (320,240), 100, Gold
Paint (320,240), Gold
