The PNG background issue i ran into was this......

If you use a PNG background.. your buttons will not display their momentary/active state properly. They dont "flash" unless you hold the button down.

Initially i thought it might have something to do with PNG graphics so i converted every graphic in the file to bmp accept for the background. At that point i was lost and posted at IP. Pedro pointed me to the yahoo group where i found someone referencing the png background bug. I changed the png background image to jpg, changed all the other graphics back to png and viola problem solved.

FYI.. the buttons still operated properly. I could control the system perfectly. The only issue was the buttons wouldn't 'quickly' show their active state when pressed. Its basically a non-issue. Who cares what format the background graphic is in so long as i can have my buttons as transparent png's.
