Lightning strike bug

Hi

There is a bug with lightning strike gem. I cant precisely say when it occurs but it cause client.exe to stop responding. Its mostly end with +1 death to my character. When I reconnect I can enter instance where I've played but some part of map (tab) is gone.

Sometimes it happened when I hit one monster, sometimes when I hit multiple monster. My friend who's using same skill has same problem.

Im using Windows 7 64bit
