Mouse position and camera scrolling issue

maxerov

I am making a game where the camera follows the player actor. A crosshair (aimer) actor follows the mouse. My problem is when ever i move the player actor enough to make the camera move. The crosshair actor follows the movement of the mouse but is offset by however much the camera moved. Does anyone know how to fix this so that the crosshair will not be offset from the mouse when the camera moves? Thanks.
