Turn Off Windows Explorer Click Sounds in Windows 7 or Vista – How-To Geek: I needed to figure this out for a fellow employee today. We are testing the automated banner rotation in an iframe on our OpenX Ad Server. It apparently does this by constantly reloading the iframe page. Annoying. I would prefer to do it in javascript and have it just reset the image “src” value. Anyway, this might help you get rid of that annoying “click” on page load.
