This renders Num5 non-functional in-game, which has broken my binds for my many-buttoned-mouse (I've bound the mouse's keypad to the numpad, and quickcast to the numpad as well).

And yes, I can just toggle Numlock when I play DotA, but I hated playing HotS because I had to remember to toggle Numlock on when I booted it, and this never used to be an issue in DotA until 7.07.

I will die on this hill.
