Spry Menu Bar works great in Firefox but Messed up in IE

http://www.businesstobusinessnetwork.com

I'm using Dreamweavers spry drop down Horizontal menu bar and it works great with firefox. However in IE the sub menu bar displays horizontal rather than vertical, making the lower level menu bar fly off the page. Strange.

I went to the adobe site and downloaded the latest update for spry which solved my earlier problems where all the lower menu bars were flying off the page. The menu bars should display as seen using firefox or with the main menu bars running horizontal across the page with the lower level menu bars appearing directly below and slightly to the right.

I would appreciate any suggestions anyone might have for solving this problem

thanks
