"We (my html contractor and I) created a website that has pop-up mp3 players on our wordpress website. For myself, they work fine. For our client, when you go to play the recording, the pop-up expands to the entire size of the screen. He has a new Windows 7 PC with Internet Explorer 8. The first screen is what he’s supposed to see, the second is what he actually gets… Any ideas on why and what to do to fix this? "
