Unlike the Gnome under the older version of SL I was using (5.2), the
6.1 version does not appear to preserve information about which
applications run in which workspace and restore it. It does preserve the
applications themselves but all start up in Workspace 1. I think this
should be under the "Sessions preference tool" according to section
3.3. of the Gnome Desktop Manual, but I cannot find any such tool....
