Running Very Slow After Upgrade to 7.1.30508.0

After upgrading to 7.1.30508.0 earlier today eMclient is running VERY slow!  Why?

I really like Emclient, but after this upgrade I am thinking of changing back to Mozilla Thunderbird. The speed and responsiveness is so bad it makes it almost impossible to get through my email.  

Please advise.

BUMP.  Same issue here and being forced o use gmail while I troubleshoot.  no resolution
