Anonymity has been abruptly unmasked

Since downloading and using the latest version of TBB, I have watched Tor unmask itself without notification, or justification on at least two separate occasions. I was able to determine this because I initially and at random times hit the home page button which takes me back to your IP check page and it said I was not configured to use TOR and my IP address was revealed. I thought it was an isolated issue, nonetheless, I have been frequently checking the home page for IP verification since that time and it happened again a few days later. Each time it said that I was not using TOR in the middle of a Tor session, when it initially said CONGRATULATIONS YOUR BROWSER IS CONFIGURED TO USE TOR. Internet didnt get disconnected and Tor message log did not indicate any problems. At this point I may go back to the previous version of TOR just to be safe. It would appear this version is either bugged or some other issue exist. PLEASE FIX
