HTML and Flex Focus Problem

I have a web page which has a SWF开发者_Python百科 file embeded. I have an issue with the focus.

Click on a HTML Text Field and Click on a Flex Field. Begin to type a text.

Expected Result is the entered text should go in the Flex TextInput field but the actual Result is it goes into HTML text field.

to me it sounds like something related to wmode in the embedding code, I would try to play around with that, I have found flash to be very problematic when replacing between wmodes.
