I was able to search and find a solution on this. Go to (in IE 8) Tools->Compatibility View or Compatibility View Settings.

>I just updated one of my PC's to Internet Explorer 8. In testing my web app, I noticed that when error icons appear on forms when a business rule is broken, the message does not display when you hover over the error icon. I checked this on the app on another PC with IE 7 and the error messages do appear. So this is definitely an IE 8 caused issue.
