I'm trying to use flex-iframe in Flash Builder 4. I'm creating a project
with similar content to SimpleHtml example. On startup, I get the
following error. Can you please advise?

BTW, I did apply the wmode=opaque to index.template.html. My mxml file is
also at the end of this error listing.

Hi yangyang, I use flex-iframe in my app and it works like a charm, haha...
That may be caused because the style in ff is handled with the "px" at the end, while in IE isn't the same
