I purchased CS5 photoshop. Operating system XP pro. From day one photoshop loads ok but as soon as i pull up a photo the screen flashes white and I return to desktop. I can not use cs5 at all. Tried down loading upgrades with no effect. Help!! I tried calling several time getting a person only once who must be from India and then they put me on hold for 45 minutes -- I had to go could not wait any longer. Is there anyone at adobe that can help me fix the problem?
