When i enter the game, i am unable to move my mouse in any way. When i tab out, it moves as normal, but it locks up immediately when i tab back into the game.
I am having the same problem, playing on Mac.
I found this thread, if you are playing on Mac it should help
Here is what worked for me:
Navigate to: System Preferences -> Security & Privacy -> Privacy Tab -> Accessibility
Click the lock to make changes if you need to (authenticate with admin credentials)
Make sure “Heroes” is checked in the list
Close System Preferences and launch the game
I did not have to scan and repair to fix the issue, I did that before, it didn’t do anything for me. Only Steps 1-3 above fixed my issue. Enjoy!
Thanks man, followed your instructions and it worked like a dream.
