Had this exact problem on two different Bravos (thinking it was a hardware issue until the new on did the same). What fixed it for me, was going all the way out to the desktop. Going to Control Panel–>Windows Devices–Bravo Throttle Quadrant–>Right Click on it to–>Game Controller Settings–>Click on Bravo Throttle Quadrant–>Settings Tab and then hit RESET to DEFAULT. Fixed it straight away.
