just some annoyances, when i use the crouch button, i can't use free look to turn my head and junk,
The scrolling thing has always been an issue,Like when you are typing and you start loading, you can't type until it's done.
I've had that before, usually on laptops when I am pressing 3 or more keys. Two laptops have the same problem. And my desktop will usually do it with 5 or more.
