Try this: - click the little icon to the right of the search bar in the addressbook pane.. That should allow you to adjust the sort order.

Hi, David; thanks, but there seems to be another issue. When I click on that icon you described a msg. opens up; " Display Address Book Context Menu". Clicking on it does nothing, ie no menu appears. As far as I know all the software is current. Also, hovering over that icon seems pretty unstable...sometimes it shows and sometimes not. Thanks again for your time! -Dan
