Okay.  I forgot who write the DLL.  I see what you're saying.  My 
misunderstanding.

What's weird is that it isn't a crash, a blue-screen-of-death, or 
anything else.  It's a total reboot, and I just can't imagine a darn 
thing in Java doing that.  I can try redirecting the output and errors 
to a file next time, if you think that'll help.

I know it works in WinXP.  I haven't experimented too much yet, since it 
takes 20 minutes to compile the Install.jar!  I'm open to ideas of what 
to change.

I can try different settings.  I think it best to remove one of the 
short cuts and that could narrow it down quickly.  I was worried that 
the SimpleConfig.class that Fabrice and I have been working on could 
cause some problem, but it's not in use at all when ShortcutPanel is 
working -- and I just don't see what could be going on in Java that 
could automatically reboot the system.

It could be any of those.  It's on a multi-partitioned system, and the 
partition was set up for testing, so it would be a pain to reinstall 
Windows, since I'd still have to go back and re-install GRUB over the 
boot block and make sure the config is okay.

I'm using Java 1.5, if that helps.
