Hi,
real html pages inside the flashplayer are not possible,
the browser and the flashplayer two different/separated worlds,
the only way would be to overlay the flashplayer with html content,
therefore the flashplayer wmode setting transparent or opaque must be used,
but this can/will reduce the rendering performance of the flashplayer,
the textfield plugin itself uses the build-in html renderer of the flashplayer,
which is very limited compared to real html,
best regards,
Klaus
