NumLock issue - while on desktop pressing numlock generates desired key - that is "v". In game it generates multiple keys at once - like 2x "Pause" + "v". This is what KeyHistory says after one press and release of numlock:VK SC Type Up/Dn Elapsed Key Window

Double zero issue - this key fortunately works the same way on desktop as in game, but it works poorly. Pressing double zero key generates two keys "f" and "b" at the same time, while I need it to generate only "f" since "b" should be generated only when Numpad0 is pressed. I have few theories why that is so but I am not sure about it.
