game screen locks if you check user profile, and the trade window is then closed

[---.CCC.---TradeFrame]

You are frozen onto the black screen (attached screenshot), even though you can use the chat bar easily.

How to reproduce
1. start a trade
2. check the user's profile
3. while the person's profile is loading, the other person cancels / accepts the trade.
4. when you exit the person's profile page, you are then stuck on this: http://prntscr.com/nzlyy5

Sometimes the chat window works, sometimes it doesn't.
