Now, before you go and flame me for being off-topic, let me say that I've checked everywhere on the Mozilla sites, searched through Bugzilla, and come up with nothing. I just upgraded from Mozilla 0.9.8 to 1.0RC1. And the next time I tried to access my zope site, the authentication would not work for any user except for the original administrator set up during installation. And even then, the management screen would not complete uploading to the browser and would not refresh. I backed down to 0.9.9, same behavior. I backed down again to 0.9.8 and everything works. I know...I know...it's not a Zope problem, but Mozilla's. But if anyone knows about this, I'd appreciate knowing if a bug has been filed against it under what subject, and especially if there is a workaround. In the meantime, I'm just backing down to 0.9.8 again. TIA. Kirk
