this is a port of the jquery ScrollPane Plugin.
Maybe not perfect, but it works for me
good plugin, for those who want to have a preview, don't forget to put ext-core.js into js folder or just use ExtCore of Google Ajax Libraries
doesn't work for me on FF, Safari and chrome on mac os x v6
sorry, it's work well within a div html but not within an extjs panel.
or i don't know how to make it works.
Really great! Worked like a charm.
