Dashboard loses connection in a browser
I am logged in to the Performance Advisor Dashboard on PTC's site. Whenever I leave the browser alone for a short period of time it loses connection. For instance: If I select to show one of the users it opens in another tab. Then if I get called away, or just get on another task temporarily, and come back then I see this in the user list.

This happens in both IE9 and Chrome 42.
I can do a refresh. Sometimes the info comes back and sometimes it doesn't. Most of the time in IE the screen goes gray on a refresh. Then I have to close that tab and reopen it after a fresh of the previous tab. Most of the time in IE I have to close all the tabs and open the Dashboard again to start all over. Chrome seems to work better but it still loses connection.
In Chrome I will also get this error.

Any idea why this happens or if it can be fixed?
