FYI: The UT doesn't work on my Android tablet (GalaxyTab 10.1)

The upper and lower panes (tree in the upper and message in the bottom) don't respect the hyperlink position when scrolled. So if I scroll the upper pane up and click a link, I'm actually clicking the link that would be under my finger if I hadn't scrolled. This, in turn, makes it impossible to click any link that requires scrolling to view. The lower pane acts the same. If the buttons at the bottom of a message are only viewable by scrolling down, then they are impossible to click. Very weird.
