So this bug has been around for years.

If you use right-click in FP mode, your cursor automatically resets back to the center of your screen.
This is particularly annoying if you are like me and use right-click as your "Info on other player" key (ie. viewing someone's name).

Please make it so that when you right-click in FP mode, your cursor does not get reset to the middle of the screen.

Edit: the issue may be related to having your "mouse look key" sent to right-click as well.
