I've installed Hearthstone with the battle.net app on my MacBook Pro.
After installing I press the PLAY button.
The battle.net app says that Hearthstone is running, but no window appears on the screen.
I see the Hearthstone icon in my dock. When I right click on it, the computer tells me the application isn't responding and I have to force quit Hearthstone.

I'm running 10.9.1 on my MacBook Pro.
I've tried to reinstall Hearthstone, but that didn't help.

Does someone know the solution to this?
