I've been having an issue lately where my mouse just stops responding in game. The game still runs normally, its just I can't use my mouse.
What's weird is that the normal windows arrow comes up instead, and I can move that around, its just I can't do anything in game.
This problem is unique to league; it doesn't happen in any other game.
My specs are
intel i3 3.5ghz
radeon R7 260x
