with HTML/CSS it is possible to create a box which has its own scroll bar by applying the css property overflow:scroll to a DIV
how do you do this in flash
(i know it can be done because i just saw it)
There are a few ways to implement scrollbars in Flash, so if you provide a link to what you just saw, it may be easier to answer for that.
I no longer have the link
Look into the ScrollPane component. That would probably be the least imposing solution for someone unfamiliar with Flash.
