after looking at this in more detail, i would prefer to fix the white square issue, I think this might be easily fixed by hiding the UIScrollBar component when the text fits in the box. When I shortened the text in the box to make it fit, the white square didnt turn into the scrollbar like it would when the box was full, it just stayed there, taunting me with its 4 evil corners.
anyway, here is the current actionscript for the layer in which the dynamic text box belongs. I'm a complete n00b at actionscript, Is there anything i can do or add to hide the UIScrollBar when it isn't needed (i.e. when the text box isn't full):
//init TextArea component
siteText.html = true;
siteText.wordWrap = true;
siteText.multiline = true;
//load in XML
newsContent = new XML();
newsContent.ignoreWhite = true;
newsContent.onLoad = function(success)
siteText.text = newsContent;
Another quick update. I managed to fix the fade issue by converting the text area and the UIScrollBar component into a movieclip symbol, inserting the xml loading actionscript into that symbol on the first frame and then tweening the movie clip.
However, I'm still having problems with thewhite box
