I've been working on an app that uses a custom skin in Flex 3. The app has a help window. The help contains an HTML with frames. Problem is, the main app vertical scrollbar custom skin is being ignored for the HTML Frames scrollbar (what looks like the classic version of Halo - maybe). This only happens with frames. It happens no matter how or where I place my HTML or HTMLLoader. If I dont have frames the custom scrollbar is used. Is there a node im missing in my skin css (obviously not VScrollBar or ScrollBar - the two standard used by Flex)? or some other way to connect the HTML Frames scrollbar to my custom skin.
