Issue with CMUCam2 Demo application

[kitscuzz]

After running the tracking frame for too long, none of the buttons in the application function. The tracking frame freezes, and even if you stop tracking and try again, remains frozen. If you try to grab a frame or start monitoring the tracking again the buttons gray-out and nothing happens. The camera remains this way even if you close the demo application and start a new instance (without restarting the camera). The camera no longer registers (as in Labview asks you if the camera is properly connected) and on the third attempt to reconnect the camera accepts the connection, but all the settings are cleared.

This does NOT happen with the earlier versions of the application.
