Gnome 2.4.2 panel problems with Xinerama

["John D. Giachero" <kickaha patmedia net>]

I'm running gnome 2.4.2 under gentoo linux, and, after a recent
update, have a panel problem I can't resolve.

My previous setup was a top panel, a bottom panel and a right-side
panel, which would show up at the right of my total viewport;
i.e., at the right edge of my 2nd screen in a Xinerama setup.

     --------------      ----------------
     |            |      |              |
     | primary    |      | 2nd screen   |
     |            |      |              |
     --------------      ----------------
                 ^                     ^
     panel is here                     ^
                       it should be here

After a recent upgrade (emerge -u, based on available update in
the gentoo ebuild database), my right-side panel now appears on
the right side of my primary screen, rather than all the way to
the right, which is what I want to see.

I tried to middle-click and drag it over to the correct location,
but it will not move.

I kind of miss the 'old style' panel structure, with different
panel types that were easier to move around the screen. :)

Any suggestions would be greatly appreciated.
