[CLIENT] game alt tabs during the first 5 minutes when using mouse button 4

every game for the last 1-2 weeks my game will randomly alt-tab to my home screen once during the first 5 minutes of the game. It always occurs one time, within the first 5 minutes, and when i use my mouse button 4 which i have set to auto attack move. i have had the same mouse and keybinding for about a year and this problem just started occurring. im using a Logitech g502 but i dont think that matters because im pretty sure it is something on the client side since this randomly started happening without me changing anything with my hardware.
