DH's Rapid Fire sometimes bug forever

I was playing with Demon Hunter using rapid fire and it bugged, I could not play ano other skill or attack and cannot leave the game. At the same time I was getting killed by the monsters alive while my Templar was killing other monsters... No matter if I run or not, I take damage as if I was stand, untill I die.

When it happen I need to Alt+F4 the game to start again...
