V7 not shutting down

I have a ‘lifetime’ license for emclient (Jan 2010) and am using Vista.
I have been trying V7 but have an issue with V7 not shutting down properly/cleanly.
I have tried the very latest version that it was hoped resolved this issue.
I’m afraid that in my case it does not.
In fact, I can not even get to taskman (rt click taskbar), I just have to wait!

I have reverted to V6 in the hope that there will be a fix for V7.
Is there a way of stopping V6 showing a ‘popup’ to upgrade/update to V7.
