when the system tray has like 8 icons in it, (or 7 depending on the size), on any theme it will drop the final slot and give you a down arrow that opens up a second row. Sometimes that row never goes away and locks the home screen and the first row from use even if you try to click the arrow to make it go away.
I reflashed my tablet, and I'm sure GIMP can handle .ani files... it handles just about any image I throw at it. Once I get the theme installed and up I'll see if I can fix this killer 1 pixel bug.
