Will not let me use "E" key.

[Smittiy]

I know it's not an issue with my keyboard, because I'll go into chat and, "E" will work, but for some reason some times the key will randomly stop responding when I try to use it on doors and such. Happens almost every day, it's not game breaking, but it gets annoying.

What server(s) is this happening on?
