For me the issue is pretty annoying: Game options will not let me change controls (I left click on the key options and nothing happens), and my computer has no scroll lock key.
So I have to minimize the game, enable on screen keyboard, bring up the game, click scroll lock, minimize the game, close on screen keyboard, open game again.
And do this every time I kill someone just in case they were playing pokemon go and their copse has a light. Kinda sucks.
