Windows 7: e-Mail Downloading Problem ?

Hi,

I know this probably isn't the best place for a question re a Thunderbird e-mail
problem, but am not sure where would be. You folks have been so helpful in the past, will take the liberty of posting here. If really a violation of the forum protocal, I apologize.

Had to do a Restore-Point, and ever since then I have the following problem.



I use Comcast for my e-mails, and Thunderbird for my e-mails "reader".

The same e-mail messages, one after the other, keep getting downloaded to my PC/Thunderbird.
I must have dozens and dozens of the same ones being downloaded.
Never had this happen before.

I looked at Server Options in Thunderbird, but don't see anything like:
Delete From Server After Downloading, or similar.

How do I get only a single copy of each e-mail downloaded, please ?

Thanks,

Seems to be a fairly common issue (not finding the option). Have you seen this?
