I had something similar a while back, the view wasn't enlarged but across the top of the screen was a stripe (the same size and shape as the advertising banner on the scoreboard screen) and the course view was pushed downwards so the club / meter etc were not visible.
I think pressing the space bar took me to the normal zoom view and pressing it again took me back to the main view without the banner.
Maybe Flash player getting a bit messed up trying to show the pop up advertising on the wrong screen ?
