Ok! I've reinstalled - twice! The first time, it imported Cleo and crashed trying to import bruce. So, using 5.9 Live, renamed bruce to bruce_BAD. Started installation, imported Cleo and created new bruce.
The beauty of this is that the extra programs I had installed earlier are still present. (/usr is a separate partition.) Unfortunately, just like each of the previous 18 reinstalls in the past 12 months, I have new issues to resolve before I can even get to the point of see if the others were resolved! For the first time on this machine, the wheel doesn't work. (Have added that option to xorg.conf but it didn't help.) SeaMonkey can't display many (not all) graphics.
Ah, Well! I could re-install - again - and see what the coin toss brings. If Caitlyn is still following this, I may have needed to reboot daily in Win98 but I didn't need to reinstall it! And, despite what I had heard as early as Slack 3, about Linux (and the later windows) having better memory management and not needing to be restarted I have not found to be true!
