Mouse Unclipping

As the title says, i have been getting this quite frequently, Where my mouse cant move my character, i can still browse the Q menu and such, But to use the mouse to move my person i have to quit and rejoin which is annoying as you lose all your props :\ any ideas?

Reset the key configs within the settings?

ok ill give that a try when i get back on later on.

Okay, let me know if it works.
