But, what did I do that an average computer user doesn't do?  There was
no prompt telling me to safely remove it, so I yanked it.  Actually, I
received this computer as part of a training course and I'm trying to
drop my expertise level so I can see what happens and learn from there.

Good!  I'm glad to see things are coming along.  I don't regularly use
either of the DEs and just use IceWM, so I haven't seen this
progression first hand.

Yes, I've seen it in KDE 3.4 on KNOPPIX 3.9, I believe.  In fact, the
list archives have a somewhat embarassing post about it from me.  ;)
