Need help with xith ui/swing

Hi,
Does anyone know how to properly implement a scrollable JTextArea using the UIWindow? I have had problems after adding a panel which contains the scrollable JTextArea. For some reason, unless I make the layout GridLayout, the JTextArea overlaps the exit button I created even when I set north and south borderlayouts. When I don’t use a gridlayout, the scrollable ability doesn’t work. Must I use the gridlayout always?

Can you create a small testcase, so we can test it and possibly submit an issue?
