Key bindings w/ Jump/shoot issue

Hi all, I am excited to let you know that I solved this ongoing issue where you enter the game and your avatar fires when you jump, you cannot sprint, and so on. Many of you posted possible solutions and I wanted to do my part and share again what another player posted here. I had no joystick hooked up, no weird keyboard or driver issues... it was all about the joystick settings/bindings in the options menu. Again, I had no joystick attached to my PC, but the bindings were there. So, it only takes about 5 minutes, but all you need to do is clear all joystick fields for all situations (on foot, in tank, etc.). I didn't even have to restart the game, and all those issues went away. Amazing fix! I hope it helps you too! Thanks to whoever did post that solution!
