Conflict with DisplayBuddy Slideshow Plugin in IE7

Hi,
I have this Plugin working great, and clients love it. However on one site I am using it while also using this plugin: http://pluginbuddy.com/purchase/displaybuddy/

I am getting this error (see screenshot...actually a photograph as my windows machine doesn't support the nice mac type screenshots) over and over again whenever the page loads.

I have disabled all plugins and this only happens when these two are present, and in IE7 (because unfortunately this site requires that I test for IE7).

Would appreciate any help & advice please.

This is also being posted on the iThemes forums.

Thanks Ab
