Ta-dah! I've found the cause and thought I should share with community and developers, so here goes. Many thanks to all that responded with ideas, too!
It turns out that during some aspect of the upgrade process from 1.53d through 1.60h to 1.60j (current), and/or deleting my "Inbox - Known" folder, *some* of my existing mail filters lost their criteria. It's not clumsy keyboard use I know, because it was a random minority of a few of my filters, no obvious pattern, and I have about eight filters in total of which most were unaffected. The upshot is that the first filter that had lost its matching criterion simply funnelled all inbound mail into the target folder. Put the criteria back in place, sorted out my inbox, and we're all back to normal. Maybe just a glitch during upgrade, but thought I should mention. -- Best regards, James. ________________________________________________________ Current Ver: 1.60i FAQ : http://faq.thebat.dutaint.com Unsubscribe: mailto:[EMAIL PROTECTED] Archives : http://tbudl.thebat.dutaint.com Moderators : mailto:[EMAIL PROTECTED] TBTech List: mailto:[EMAIL PROTECTED] Bug Reports: https://bt.ritlabs.com
