So I started playing in 2012, and recently started replaying this game because it is one of the few games that don't require a download. I wouldn't mind that if I didn't have a dinosaur of a computer, and a mac. Bad combo. Anyways, it worked perfectly before I quit, but now I can't stop running unless I crouch/jump. This wouldn't be a problem but it affects my wall jumping abilities. I let go of the key and it just keeps running in the game, instead of just standing there. No, I do not have "sticky keys" I clean my keyboard because my sister gets it greasy sometimes. I don't know the problem at all, help?

Hmmm,Have you press left/right and click the chat space
Or did you keep going on when you just stopped pressing the key
Either of those happened to me before.

Nope, nothing is clicked.

Is this very often? Even after relog?

Yup, it does it every time. I've logged it countless times.
Also I've found that bite doesn't work when playing traitor. Yes, I'm pressing space.

Have you tried testing with another keyboard to see if it's a hardware issue?

Indeed.
