I did an apt-get dist-upgrade, to move from 2.1 to 2.2r3, then did an apt-get install kernel-image-2.2.19, based on a recommendation from this mailing list.
My problem now is that when I start Mozilla it takes 50 to 60 seconds before the application appears on the screen, and all the time I can hear my hard drive "thrashing." After that any activity in Mozilla (such as clicking on "file" or "edit") takes about a minute to execute. If I were using Windows I would assume that the operating system got trashed again and I would reload it for the umpteenth time. What could be happening here? I think I may be ready to buy a set of 2.2 disks because from a beginner's viewpoint it seems that successfully upgrading the OS to 2.2 was probably too much to expect. It went very smoothly (I was very impressed with how easy it was!), but I did get some messages about what seemed to be housekeeping tasks that needed to be done as a result of the upgrade. Some of them related to files that simply don't exist on my machine, so maybe something is seriously wrong. Anyway, I thought I would post this question here just in case it's an obvious, easily fixed problem. Otherwise, I'll just re-install from a new set of disks. By the way, my computer is a Pentium 200 MHz, with 32 MB of RAM. Is this too antiquated to run Mozilla, or perhaps Gnome or Galeon eventually??? Thanks, Peter Christensen
