POE not responding after minimizing

As of the most recent patch, each time I minimize Poe so go to trade, when I return to the game, the screen is black, forcing me to open task manager which reports the Poe is not responding. At that point I end Poe and restart the game. Thanks for checking into this problem.

I am also seeing this behavior. When I ALT-TAB to my second monitor for something the game becomes unresponsive and I have to end it through Task Manager.

I experience exactly the same problem. It's more viable for me to simply quit the game and log in again than to alt tab, because steam and poe become completely unresponsive. When I finally can interact with the game, I am logged out.
