Mountain Lion POP3 stops downloading

Question

Mountain Lion Mail POP3 connects to the server, appears to download 39 messages, but doesn't. 
Here are the steps taken so far:
Ran Connection Doctor.  All accounts (POP3, SMTP, iCloud) connecting.
*^ Click* on *Inbox* to *Get Account Info*.  Result displays messages on the server; Mail won't download.
Close Mail; reopen Mail.
Reboot user account.
Restart computer.
Ran Disk Utility to verify/repair permissions; verify disk.  No issues.
Removed files from Inbox.  Check mail.  No change:  files on the server remain on the server.
Backed up files, deleted account, then recreated account.
No change.
Via web mail interface, server side is functioning correctly.  Email comes in; email goes out.
Also, when I manually *Check Mail*, often there's no indicator that nothing is happening (i.e. accounts are being checked); less often, I see the usual signs that each mail account is being checked.
No problem (yet) with outgoing mail. 
Please advise, and thanks in advance.

Here's a document reference, although it sounds like you've tried many of the steps they suggest:

To me, this sounds like you may have an issue with the incoming mail server name.  I found that for my POP mail, Apple added an extraneous ".yahoo" to the string now suggested by the mail service provider.  I would start by checking there -- in Mail ---> Preferences ---> Accounts
