not all emails checked Rated 3 out of 5 stars

This addon became essential to me, i love it dearly but a week ago (or so) my primary yahoo email became uncheckable. I have no idea what's wrong, there are no messages, no popups, no nothing, but when i tell it to check my email, this one consistently stays unchecked. The funny thing that when i click its name, the email page opens without any problems showing new messages.
I have 2 yahoo emails and for some reason the one that i most care about always shows in red (aka 'not checked'). Shame, real shame. I hope we'll get an update to this soon!
Until then 3 stars only.

This review is for a previous version of the add-on (1.1.7).
