konsole trouble

[Robert Singleton]

I'm running Fedora 10 under the Gnome desktop on a Toshiba laptop. Last 
night I seem to have messed up the konsole application (not sure how, 
but I think it turned dark, wouldn't respond, so I killed the app), and 
now it will not launch (although Terminal will launch, but I don't 
really like Terminal). The problem is also present with other user 
accounts, so it doesn't seem like it's a local profile setting. The 
Microsoft fix of rebooting does not solve the problem either. Any 
suggestions? Thanks very much in advance if you can help me.
