really?  Wow.  I haven't seen that with feisty but then again, since the X11 
server is mildly screwed up, I don't use that particular laptop much anymore.  I 
can't wait until a certain package I depend on has been ported to Linux via 
wine.  Then I can get a quiet farewell to you know who.

I'm wondering, could this be used with a server?  What's the tool name?  Reason 
being is I have a shuttle box sitting on the shelf behind me.  The fan blows on 
the wall and is starting to peel the paint with mild charring of the shelf.  Can 
you you tell it has a 2.4 GHz Pentium 4.  :-)  challenge will be that it is 
running dapper alone if I put the raid in and upgrade VM Ware server (yet 
again), maybe, just maybe...
