If you download Adobe Flash Player 10 on to my partner's computer, then when you visit, say UTube, for example, the screen is taken up with advertisements and then to enable you to see a screen which is normal you must disengage the Adobe Flash Player 10 and you are then left without any Flash Player at all. It was previously Adobe Reader 9 which gave no problems, but we were asked to upgrade. The operating program is Windows 7. What can be done to rectify this?
