Theater Servers cause me to Crash

It is happening a lot recently and its the kind of crash that Alt+Tab or CTRL+ALT+DEL can’t get you out of.

My screen goes black and everything becomes unresponsive. I have to hold down my power button and turn my system off and then on again to get my system back.

It is likely due to the flash videos but it has never been this bad until recently.

Anyone know a way to stop these crashes?
