At this point, all possible problems related to Internet Explorer 8 are under evaluation.

We are continuously monitoring the IE8 development news but we cannot provide definite solutions to problems that may be solved by Microsoft in case they make further changes to the way IE8 behaves when active content rendering is involved.

As a temporary solution to the IE8 related problems, the "Document Compatibility" mode can be used as Microsoft explains in an MSDN article:

Specifying Document Compatibility Modes

To specify a document mode for your Web pages, use the meta to include an X-UA-Compatible http-equiv header in your Web page. The following example specifies IE7 mode compatibility.



<!-- Use IE7 mode -->

<meta http-equiv="X-UA-Compatible" content="IE=7" />

<title>My Web Page</title>



<p>Content goes here.</p>



The content attribute specifies the mode for the page. Specify IE=5, IE=7, or IE=8 to select one of those compatibility modes. You can also specify IE=edge to tell Internet Explorer 8 to use the highest mode available. If you specify other values for the IE attribute, Internet Explorer attempts to convert those values to a version vector, and selects the mode closest to that result, as shown in the following examples.

<meta http-equiv="X-UA-Compatible" content="IE=4"> <!-- IE5 mode -->

<meta http-equiv="X-UA-Compatible" content="IE=7.5"> <!-- IE7 mode -->

<meta http-equiv="X-UA-Compatible" content="IE=100"> <!-- IE8 mode -->

<meta http-equiv="X-UA-Compatible" content="IE=a"> <!-- IE5 mode -->

Note The previous example shows the results of individual content values. In practice, Internet Explorer only respects the first X-UA-Compatible header in a Web page.

The X-UA-compatible header is not case sensitive; however, it must appear in the Web page's header (the HEAD section) before all other elements, except for the title element and other meta elements.
