Seriously, no one has this issue?

Marc,

Since your SmarterMail license key has Maintenance and Support on it currently, you may want to open a ticket with our Support team and have them take a look at your installation.

I’ve just checked on my mobile and the Message Activity stats appear to be updating every 2-3 minutes.

Are you seeing no updates here at all? Or do the updates stop after performing one of the actions?

I am saying that on this screen in the right side actions menu. While manipulating that menu it will stop responding all functions in the browser window for an undeterminate amount of time. This happens everytime I use those features and its been since sm16 builds.
