Never apply CSS while to textarea using styleSheet property

var myCSS:StyleSheet = new StyleSheet();
TextArea.styleSheet=myCSS;


Instead of attach to TextArea add CSS related code to HTML code.

i.e.

TextArea.htmlText("html tag with css class just like your normal HTML")

will work in all type of browser and scenario where you are fetching RSS feed into TextArea (which will get reloaded every time you have new feed)


Enjoy.
