Meralux

Windows 10 Professional, 64 Bit Client, no previous versions. Game functions normally at first, if I alt tab even once at any screen including the login screen, I am unable to move my character after any map transition until I alt tab out and back in again. Pokemon battles are fine and I am able to move after still. Tried running in every compatibility mode, with and without admin, toggled literally every option on or off, it's a straight up coding problem.
