MW 6.5.4 - Win 7 - Mystery Logon pop-up?

[standsalone]

Greetings all,
Lately my MW has been popping up this Logon dialog during a Check Mail scan. It's been a while since I messed with MW's innards and so far I've failed to find the source of this annoying pop-up. I'd be grateful for any suggestions.
Thank you and have a good Christmas & NY.

Hi there

Under Tools >> EMail Accounts >> do you have an extra email account listed ?

Thank you rusticdog! So simple with another pair of eyes I was wondering why that empty - was there.
