In "fly" mode I spin in a circle dispite not holding down any other buttons, keys or moving the mouse.

Holding down RMB puts me in Fly mode in which I can walk around like in the normal Hubs experience (or should be that way, at least.) For me, however, my view immediately starts rotating counter clockwise as soon as I press RMB. The spinning continues as long as RMB is held down, even while I move the mouse and walk with WASD. It's not a showstopper, but it is really annoying.

Here's a screencap:
