This will be vital for groups containing more than 15 or so members, especially since the OK and Cancel buttons are located at the bottom of the modal panel. A horizontal scrollbar shouldn't be necessary, since the content is a table with a fixed width. See http://jboss.org/file-access/default/members/jbossrichfaces/freezone/docs/development/faq/en/html_single/faq.html, item 1.32, for info on how to add a vertical scrollbar to a RF modal panel.
rev3130 - allow drill down to scroll when necessary, for large groups; ian, i couldn't access that link so i solve it using an overflow-y style on the modal panel, which is built up programmatically in the ConfigRenderer. not sure if that's the suggested/standard approach, but it worked well. let me know if you think it needs to change.
