It mostly happens on my WW barb, but has happened once on my DH. At some random times, my char will become locked out of any keyboard interaction. If I'm WWing when this happens, my char continues in the direction they were heading when the lockout happens, and no button (mouse or kb) works, EXCEPT right-click. Since for me this is my WW button, my char will only spin around. I can't move them, or even pause or leave the game. The only way to fix it is to force-quit the game and log back in. This is a brutal bug, and I'm not sure what might be causing it. Please look into this.
