For example … look at http://www.zakenwijzer.nl/opleiden/index.html (dutch, but who cares). At the right you’ll see a couple of downloads. Hovering above it results in a small text box.
I currently have a number of graphic items that I have made as buttons with a hyperlink and title. All works fine in Safari/FF with hovering and title display but when I port my Site Folder over to Vista IE7 via VMWare and hover, it is actually displaying the graphic item item value, such as button1 or button2 etc instead of the item’s actual hyperlink title.
