Phys Gun can't rotate horizontally

Whenever I pick up a prop or ragdoll with the Phys gun and hold the use key to rotate it, I can only rotate it up and down. Whenever I try to rotate it left or right with the mouse it nothing happens. I can still look around with the mouse and I can rotate props by holding my use key and strafe keys.

Never mind, I fixed it by disabling my joystick.
