Hi,
for "data:" support you would need to use the latest 1.0.8.14 pre-release:
http://krpano.com/download/beta/
beside of that - the possibilities of Flash Textfield are difficult to port to real html,
the css styles for sub elements may not work in most cases,
for the moment I would recommend just using "p{ ...styles... }" as css style,
and putting all html content in "[p] ... html... [/p]",
this should work almost the same in Flash and HTML,
best regards,
Klaus
