ie7 flash iframe wmode opaque bug

use flex-iframe(http://code.google.com/p/flex-iframe/) to embed a html page into flex app. it is recommended to set "wmode","opaque". work fine with firefox, chrome, even in IE8, but not good in IE7, the textfield can not gain focus.

solution : in IE7, not set "wmode","opaque". seems to be fine now. but in firefox ,you have to set "wmode","opaque". so in your index.template.html, use conditional Comments in Internet Explorer.

if has good idea, please feel free to tell me.
