Hit only one monster while using Enrage and Game Freezes

I have a problem when using enrage. While Enrage is active, I can only hit one monster instead of 3 or more monsters. Without using the enrage skill, you can hit 3 or more monsters. After I played a while, my game just freezes. I am using windows xp.

The only thing wrong with what you just said is that your game freezes.
