TinyMCE losing frame in IE8

Question

I have a website. We use TinyMCE as our text editor. I just upgraded to the latest version and added a media plugin so our users can add videos to their names. The update works fine on Chrome, FireFox, IE7. However, it does not work with IE8. The frame around the editor disappears along with the toolbar.

Here is the initialization code I'm using:

    tinyMCE.init({
    // General options

    mode : 'exact',
    elements : '<%= txtArea.ClientID %>',
    theme: 'advanced',
    relative_urls : false,
    verify_html : true,
    apply_source_formatting : true,
    plugins : 'media',
    //valid_elements: 'a[href|target=_blank],#p[align],strong/b,em/i,u,div,br,-span[style],' 
    //            <%= AllowImages ? "+ 'img[longdesc|usemap|src|border|alt=|title|hspace|vspace|width|height|align],'" : "" %>
    //    + '-ul,-ol,-li',
    theme_advanced_buttons1 : 'bold,italic,underline,separator,link,unlink,separator,bullist,numlist,separator,outdent,indent,separator,undo,redo,'
        <%= AllowImages ? "+ 'separator,image,'" : "" %> + 'separator,code,media',
    theme_advanced_buttons2 : '',
    theme_advanced_buttons3 : '' 
});

Any ideas what I did wrong?

Jake raised the point in the comments that this was a caching issue.

As indicated in the comment, the parameters for operation include a clearing cache and including a date / time query string.
