when you are reading files and go to look in the archive and come back to file lister, the blue bleeds over the screen. might be a quick fix in the deafault.txt?
If you have the background color to something not black and you clear the screen, the screen will be the color of the background.
You may just need to make sure you're resetting the background in your file list template. You can put a <pipe>16 at the top of it to fix that up.
