Thanks for the reply, RtC; that's what I was looking for. What had happened was that I got a new HD and transferred OS 9 system to it before installing Jaguar. Something was wrong with the "Desktop (Mac OS9)" file I duplicated, and it didn't show up on my OS X desktop. I wasn't able to delete it without Root privileges.
