Installed jedit41install.jar on my Win2k (SP4, all recent
patches) machine with j2sdk1.4.2_04 running.
Wasn't paying attention, installed package into '/Program
Files' by accident (as opposed to /Program Files/jedit).
Went to un-install package through Add/Remove
programs and it blithely deleted just about every file it
could in /Program Files and beneath it.
