Thank you for the response Tommy. Actually, this wasn't the only problem I had after upgrading to Karmic. Firefox kept crashing. I reported this bug and got a message asking me to report it using apport. When I did that I got an error message telling me to upgrade tzdata. When I did that I fried my hard drive. Currently the affected pc won't boot up. I'm going to have to use the Karmic disc to attempt to retrieve my files. I have another desktop running Karmic which is also buggy. Ultimately, I think my solution to the problem is to do a fresh install of 10.04 from a disc, butn in the meantime I'm travelling for 6 months, so I won't be doing anything until June. Karmic was not a success from my point of view. 2010/1/28 Tommy Trussell
