Flash not displaying with JS in IE

I have a site with a Flash presentation and a Javascript widget displaying over it. It had been working fine however now the Flash is not displaying with the widget in IE - all versions I have looked at.

My feeling is that the JS in the widget is somehow causing the problem - if I comment out the widget the Flash displays - but I cannot see where that is. I can view do not have access to the widget code - it resides on the provider’s server.

If someone could take a look and advise me it would be much appreciated.

This is the page with the widget on: http://www.theplazasuites.com/index.html
This is the page with the widget turned off: http://www.theplazasuites.com/home_test.html

Thank you.
