Now, IE 8 supports this capability so I have the feeling that the users reporting the issue may have had Internet Explorer running in a compatibility mode to support a lower version. Fortunately, I was able to resolve the issue by add the following <meta> element to the <head> element of the master page that I was using:
<head id="Head1" runat="server">
...
<meta http-equiv="X-UA-Compatible" content="IE=Edge">
... </head>
In case you're curious, this <meta> tag, specifically "IE=Edge", tells IE to utilize the latest version of Internet Explorer available.
