Any help appreciated. Just performed registry cleaner, and now having issues with the mouse. When FSX loads, the entire screen is shifted over, and moving the mouse at the perimeter of the screen field shifts the screen to and fro, up down, etc. In flight, while CH Fighterstick works fine, using the mouse to click buttons, etc. also shifts the entire screen up, down, side-side, etc. -- chasing object driving me nuts. Prior to this, as usual, mouse would work fine to click items within the screen, but not move the entire screen itself around. Any help appreciated. Greg
