Using build 19991202 on win99, linux and mac, clicking on the address books or the addressing buttons (To: CC: Bcc:) in the Select Addresses dialog causes the page to scroll to the left, continuing this you will eventually lose your OK and Cancel buttons. On mac in a 1024x768 resolution, the Ok button is gone off the page with the first click of an address book or click of the To: button so you can't OK the dialog rendering this dialog is usless. 1. Launch Messenger 2. Click on the New Msg toolbar button 3. Click on the Address toolbar button 4. Select a Card in the right pane 5. Click on the To: addressing button Result: the page scrolls to the left (also name is not in bucket different bug 20717) Expected: the page not to scroll to the left each time you select a name and click an addressing button or not to scroll to the left each time you select an address book

Fix checked in. Problem caused by changes to flex on xul elements. Added some min-width statements to allow layout to work.

OK using dec10-08m12 commercial builds on linux 6.0, NT 4.0 and mac OS 8.5.1
