I had a strange problem with firefox 3, it would be fine to start with (after the pc had been rebooted) but then after opening a number of windows it wouldn’t refresh correctly.
Tabs would merge and it all went horrible. I’d have to close down the browser, reboot and it would be fine for a bit longer.
I uninstalled all my addins reinstalled same problem.
It wasn’t until I was using that PC remotely that I noticed it didn’t happen when using logmein. That’s when it dawned on me that the problem occurred when when logmein was running in the background. The next time I had the problem I shut logmein down and bang the problem was gone.
Logmein was causing it. I stopped using it for now.
