Mega menu not displaying submenus on IE9

I am designing an eshop based on YourShop template on joomla 1.5. All the development and test has been done using firefox 15 and I had no problems. Today I tested it on IE9 and I cant see the submenus of the main Mega style menu. On firefox and chrome everything is OK. I disabled one by one all the 3rd party modules and plugins but without any success. The domain is: www.emmanuela.insyst.info. I would appreciate it if you could help me find a solution to this problem.

Thank you in advance

Hi

I've check with IE9 and i don't see problem
What you show me some screenshot ?
Meanwhile you could try checking your IE compatible view configuration.

Sorry for waisting your time. It seems that I hadn't cleared the cache of IE thoroughly. After a complete delete everything is back to normal again.
Thanks for your effort.
