I made a visual aid to empesize my problem. Before I started editing the pallete below the JJ2 sprite colors, I didn't have a problem, but when I started editing below the sprite colors, to make a textured sky... somewhere along the line, I came across a problem where some of my tiles were surrounded by black space that acts just like an area with no background. Ah, I did use the top colors in the pallet, though, this may be linked with my problem. There is the upper left color that I used as an almost black color to do black outlines, and I may have used another top row color for a transparent color (0,0,0 black).

Anyways, this may help the diagnosis:

I've given up for now, 'cause I fear for my computer's safety. I'm just about to throw it out the window, and that wouldn't be good 'cause in the words of Mr. Dink, its "Verry Expensive. Hu hu hu."

*sigh* I'm also supposed to make sure my sky colors are pretty different from my other colors... Thats a problem, 'cause I like to use so many colors. Maybe I shouldn't make a textured background. (but this error shows up textured background or not)

The error shows up in 16 bit, 8 bit, and only in windowed mode. It didn't show up in full screen mode.
