Players sometimes can't move in-game

[foonull]

Sometimes players report that they can't move when playing halo and their keyboard control don't work but they can navigate through the menus, and everything else. Not sure what is up and how to reproduce the issue.

I noticed that I can move forward by pressing Z instead of W, not sure why.

I am having a similar issue, where no keyboard input is being recognized, including escape, enter, or movement.

Only started happening a couple days ago. No changes have been made to my keyboard/mouse.

+1 issue still exists. No keyboard inputs are recognized by the game.

I've had this issue. By chance I quit Chrome and it started working again.

I had this issue as well. The problem was that my antivirus software (Symantec and Webroot) were running kexts in the background. Getting rid of these fixed the issue.
