Hopefully this will be an easy one to answer:
Some times (well in some files) when I select a sprite in 2k it has extra sprites floating around in the background. But when I open up the file in CS4 it shows that there are no difference between the color value of the background, anywhere. . . So why am I getting these magical floating pixels?
Also, does the color of the background have to be anything in particular? I've just been completely removing them to save any confusion on my part. (For example, if you don't know what I mean, there is no information in the background anymore, it's just the checker board in CS4.)
