If you have n rows where the heights of the rows add up to more than the height of the List, you should see scrollbars on the List. If a row's height is greater than the list, it shouldn't matter to the scrollbar calc, but you can't see the whole thing due to lack of fractional scrolling. Fractional Scrolling is unlikely to ship with Moxie due to time constraints. We think we've left the hooks in there to make it work, and hope somebody will get it work and post how to do it. -Alex

I ran up against the same wall in another part of the application. Am I correct that this is addressed in Moxie Beta 2?
