Thanks for your post.
I'm not entirely sure I'm understanding the problem fully. Is it just that the blue indicators keep spinning? What happens if you go to the commit tab?
The blue indicators rely on a polling query we run every 60 seconds by default. This is not actually necessary for the functionality (it might just be a really expensive query in your case), so if you want to turn it off, you can follow the steps in this article: http://documentation.red-gate.com/displ ... g+interval
If you're actually getting an error on the commit changes tab, can you send in the error report and include your email address in the prompt? That way I can look it up in our bug system.
If no error report prompt comes up, we also have a ticket open for you (reference 17376), and it'd be helpful if you could reproduce the problem and send me your log file (you can find it in "C:\\Users\\youruserprofile\\AppData\\Local\\Red Gate\\Logs\\SQL Source Control 3").
