Re: Did not place crouch on mouse 4 button but respond

Hi @orbit7601, 

I do remember seeing a similar report like this in the past. It sounds like the game is registering that mouse button as a different key. 

Have you tried starting up your PC in a Clean Boot before running Apex Legends? If there is something else that is causing problems with the mouse inputs that may help. You can find more information on how to set up a Clean Boot at the EA Help website. 

Let me know how that goes when you have the chance to give it a try. Thanks!
