Pull down menu help

I am having trouble with my pulldown menus working in IE for the PC and aslo Firefox for the PC. Everything works fine aon a MAC.

In firefox, the menu stays a fixed distance from the top of the browser window and when you scroll up or down it stays fixed floating over the web page instead of staying fixed in postion on the page.

In IE for th ePC, the pull-down menus float up instead of down. I think it may be a CSS issue or a problem with the div tags. Can someone please take a look and help me. Thanks so much.
