Bob/KK,
I've not come across the login issue you've had. Is it possible the computer had been turned off for some reason? Perhaps for an update of some kind? That seems to be the only time I've had to re-login. As Kermit mentioned, I suspect something to do with cookies and/or security settings.
Mike, I've not been able to duplicate the issue with Quoting. It works just fine for me when quoting from someone's post. However, when trying to quote from another post while in the edit screen it doesn't work. But, honestly, I can't say whether it worked before or not. I never tried that feature.
Thanks for the reports everyone.
I'm down to the last few (about 500 or so) errant posts. It seems they will all have to be done one at a time.
Kevin
