Marksmen that train in TT: Strange disconnects?

While training in Time Temple, I've been disconnecting a lot. On closer observation, it seems that it only happens after I use Blizzard immediately following Dragon's Breath, though not every time.

Has anyone else been experiencing similar disconnect issues? I suspect Mortal Blow is to blame somehow

-cough-

That disconnection has been there ever since I have become a Marksmam (May 08?) Still easy to avoid, use Blizz AFTER db.

At second poster:

Okay, fine. Maybe I'm a little slow. I've just never had this happen before.

pretty common, just take a step after db and then blizzard, it will mostly avoid the bug
