Flash Transparency Drop Down problem

Hi Everyone,
I had posted a query for same project earlier which i got solutions too but now i have come up with another problem. I have a transparent flash and html combo boxes always come in front of the flash. Is there any such method where dhtml combo boxes or custom combo boxes can be prepared and used instead. Its ok if the script works in IE and Netscape 7 onwards. If not then is there any other solution other than hiding the combo boxes…That would be cool too.

Once again in Brief.
I have a Transparent Flash with 770 x 600 w/h and a drop down list /menu(combo box) that comes up front of the flash.
