iMac OS X version 10.6.8 - Up to date Flash Player 11.7.700.169: Videos show the Adobe Flash Player Settings info box in the centre of the video screen. I have realised that adjustments are made to the permissions or preferences on the Adobe Flash Player Site. (I do not fully understand the effect of these "choices.") The settings box continues to obscure the video screen. It is unresponsive to clicking the Close button. How should I clear this settings box from the screen?
