Guest Issue Ad Header making games unplayable!

I have enjoyed playing games on POGO for years. Recently while attempting to play Scrable and other games i have encountered an advertising header at the top of the loading screen that dominates enough of the screen that i am unable to access the buttons that i need to click on to start the game. and, since the option to go to full screen is limited to members only, i have been unable to play any games for several weeks.
