Anyone else getting this?

I buff venom, blade shield and fade. My left click is whirlwind and when I switch my right to dragon flight, I am immediately booted to the chat area. I switched it too so my right is whirlwind but as soon as I switch the left to df, boom, back into the chat rooms.

I'm using the following:
andariel
+2 rare ammy
two chaos claws with df....

Nevermind guys, I figured it out, it was because I was clicking on a skill that I couldn't actually use because my strength was too low. The claws were equipped but they were red (not enough strength).
