Flash has a property called "windowing mode" or "wmode" for short. This controls how the flash object is rendered by the browser. The default mode "window" causes the flash object to render on top of any other element on the page, regardless of frames or z-index.

You want to get your 3rd-party flash object to render using wmode=opaque or wmode=transparent so that it will render correctly in the browser and respect z-index order (the different between these two modes is whether content that is under the flash object can be seen through transparent areas of the flash).

See this Adobe knowledge base article for details.

edit: If you control the iframe content, you can force this mode yourself.
