Basically my problem is the site I am working on has a horizontal drop down menu and I am implementing a flash chart on the page.
When you hover over the menu the items drop down behind the flash chart and are unclickable. Can I get around this somehow?
bgiframe is a jquery plugin that will allow you to do what you are asking; You can do this without jquery (obviously), but the plugin makes it really simple. Technique is basically to add an IFrame around the content you want to show over top of the flash (this also works for hovering content over dropdown lists).
