This is a bit similar to the spell check problem on kmail only much shorter duration. Basically 10 to 12 active tabs and I open a fresh window from one of those from time to time. May also open tabs in that. Then close it and go back to the main one. ;-) works for me. The main window has been up for 14hrs but don't think that has anything to do with it. Several times while using firefox in this way it hangs for maybe a min or more and then decides to catch up. I have also had a black screen for a few seconds on several occasions while using various apps. Are these related to power save by any chance? I have used pc for a long time so always disable them. I might spend many mins reading and thinking about something or the other and the start up time gets annoying. A desktop power save button to activate it would be far more suitable. holp - it was working a few secs ago - spell check not here again. was a few seconds ago - UNDERLINING WORDS WHILE I TYPED THEM RATHER THAN WAITING FOR THE END Notice all caps also goes further across the page.
