I just downloaded Firefox 1.0.4 onto my Win 2000 system. A problem that I ran into fairly quickly was that the browser would hang when I clicked on the "Go" pull-down menu (and occasionally on the "View" pull-down menu. Looking at the task manager, I see that the firefox process has got high CPU usage (upper 90s range), it's CPU time is going up very quickly and steadily and that its memory usage is rising rapidly. Has anyone else seen this? Is there some sort of fix for this condition? Thanks.... Jim Lahue
