Free TextScroller. I was looking for free, lightweight scrollbar to use with Flash Text Formatter. There are quite a few out there but good ones are either part of commercial set or too heavy(MM UIScrollBar), so I made my own. It is less then 4Kb compiled AS2 component, compatible with Flash Player 6, 7 and 8(8.5).
Getting basic scrolling to work was quite easy, but polishing all of the details (fp6 compatibility, livePreview etc) took much more time. It scrolls textfields horizontally and vertically. Check out the example:

To change the default skin just insert library identifier name of the skin movieclip in component's parameters panel. Skin movieclip should contain movieclips named as in image below.

And here is Actionscript Reference List:

Properties:

• autoHide:Boolean
• fixThumbAtEnd:Boolean
• targetTextField:Object
• orientation:Boolean (true for horizontal)

  Methods:

• setSize( w:Number, h:Number )
