Menu button becomes defunct occasionally after use

[Janibal101]

Haven't pinned down the exact conditions that cause this over the year that I've had this issue. But, when it happens, I have to switch to the the standard launcher in settings and back to Olauncher or restart my phone to fix it. The menu button refers to the square button in the OS tray when using the 3 button (not gesture) controls. I saw a closed issue for something loosely similar that leads me to believe it's an OS issue but it'd be super cool if it wasn't all of a sudden.
