When in film viewer, I try to maneuver around the screen and have found out that my up/down arrows do not work to move me forward or backward. I have to "turn" sideways and use the left/right arrows to move forward and backward in the film. Also, after a few minutes of doing this, I get a "dinging" sound everytime I try to use the left/right arrows. My default views are Internal and Pan. Is there a film viewer download so I can re-install it or do I have a buggy system and have to deal with it? Any other suggestions? Thanks.
