Thanks Guy, that's a big help.

Attached is a new version that's a diff against current CVS. I think 
it's much more intuitive (Thanks Richard U. for suggesting it.). The 
patch changes the UI so:

1) the CList updates as you enter/modify options.
2) Windows users get OS descriptions in the displayed devices list.
3) the lists now display at least 5 rows.
4) there's no longer an "extra" CList for storing edited values. :o)

The only thing (feature?) that's gone now is if you've disabled or 
removed an interface, your previously saved options won't be displayed 
or saved if you select "OK". I don't think this is a big deal though. I 
was probably thinking too much on this... :o( Oh well. If you're 
shuffling interfaces around between machines and/or bringing them up and 
down often, it's probably easier to just edit the preferences file 
directly. (I hope I do this more than the average user. ;o))

Maybe Graham will have some time to test this out? (Thanks again Graham.)
