Thanks for the very helpful responses. Can't believe that I had never heard of CTRL+ESC before. That was very revealing, though I don't know which items in that list I could safely remove/kill/delete. Is there some way to save a copy of that list to a text file? My system is a Thinkpad with 1.86GHz processor and 1.5-gig ram I don't know how determine how much "swapping to disk" there is. Could not find any file named /var/log/messages? Thanks to the CTRL+ESC tip, I could indeed see that some processes are consuming a lot of memory (like krunner), and that is one reason why I'd like to be able to post the list that CTRL+ESC reveals. One more very strange problem, I uninstalled and reinstalled Firefox and then it worked once and then apparently vanished again. It appears in the menu, but when I click on the menu icon, a desktop firefox icon bounces for a few seconds (how to stop that annoying effect?) and then vanishes and firefox does not load. ----------- Brian wrote: > A runaway task would be my guess as well (Ctrl + ESC is > your friend).
