Do you know when it changed? Do you have an idea of what you've all done to IVAN's folders and files or your computer between the time it looked normal and the time it started looking messed up? Do you have any suspects (as in, it looked fine until you did/downloaded X, then it got screwed up)? What system are you running IVAN on (DOS, Windows, Linux, possibly Macintosh with Boot Camp or another Windows emulation program for Macs)?
