I'm afraid not. The responses here were largely just repeated over and over, when many of them clearly had not read the thread all the way through.
I did (on my own) manage to get the SEF urls down to one per page, but they insist on generating at the highest number, so instead of:
www.yourdomain.com/aboutus.html
It says:
www.yourdomain.com/aboutus-63.html
Going into PHPmyadmin and emptying the jos_redirection table on your own (not using JoomSEF's backend to purge) helped temporarily. My site is back up to 86 000+ pages already though, in the month since I've done it (we only have about 600 articles, so explain that).
Anyway, I've been working on upgrading to Joomla 1.6, and do not plan to reinstall JoomSEF. I'll be going to sh404sef.
Best of luck to you. My experiences (as well as my co-worker's) has lead us to leave Artio products well enough alone, unfortunately.
