Mail Activity Window - Won't Stop Receiving Headers

[mikemalphurs]

Hello-
I have been having a problem with Mail and its Activity window. The first problem is that at least once a day I look at the activity window and it says

[Inbox - Email Account Name- IMAP] Fetching New mail Received 512 of 18446744073709551615 headers...

And it goes on like that forever until I restart Mail.

The second may be similar to this (or even the same thing). I will look at the Activity Window and it will say

Receiving 23 of 25 headers...

It will get stuck like this until I restart Mail.

This has been going on for a long time and is quite aggravating. Any help would be much appreciated!
