I have been running OE6 for several years trouble free. About two months
ago, I started getting multiple copie (up to 10 sometimes) of the same
messages in my Inbox, but I haven't made any changes to OE. The box on the
Advanced tab of the email account "Properties" that says "Leave a copy of
messages on server" has never been checked.
I have been running Cloudmark to detect spam (and it works great), and AVG
Free to detect viruses, both of which seem fine. My ISP watched the messages
on their server while I watched them download onto my computer, but they
didn't get deleted from the server for some time.
A typical event will show emails downloading (1 of 33, for example) from my
ISP, then ten minutes later the same emails will download, plus any new ones.
Eventually the copies stop, but it's a pain.
What's the best solution here? I'd like to keep my present messages and data.

Thanks,
Mark
