2.5 site displays fine in all but IE7. Sidebar Widgets Suspected

Hello,
I have a site at https://senjomarketing.com that I recently upgraded to 2.5. It displayed correctly in IE 7 and FF2 before upgrade.

After upgrade, I wanted to make my life easier so I widgetized my sidebars.

The monkey wrench is that I’m a mac user and I did NOT check it in IE 7 just after upgrade and before widgetizing my sidebars.

It still displays fine in FF2. Here is the link to the validator which it now fails miserably:
https://validator.w3.org/check?uri=http%3A%2F%2Fsenjomarketing.com&charset=%28detect+automatically%29&doctype=Inline&group=0

I should mention that I’ve done a lot of work with the WP WYSIWYG editor in 2.3.3 which has gobbled up and spit out more code than I care to mention. I’ve heard the 2.5 editor no longer does this.

Thank you in advance for your help.

Jeff
