Restarting X is the only way to regain control of the panel apps.
NOTE: this situation only happens once. Upon restarting X, user can
execute the same commands described above and the panel apps will not
This isn't all you are doing. I'll bet that you are configuring and
starting a DHCP-enabled ethernet interface, which is changing the
hostname of the machine. GNOME requires that the hostname remain
the same because the hostname is used in authentication. Our
default X security method, xauth, is exactly the same. There is
no simple way to fix this, and certainly no reasonable way that I
can think of. It should not normally be an issue, as the ethernet
device will generally have already been set up (from install or
kudzu) and the hostname already set by the time X is running.
If my assumption about what you were doing is wrong, please
re-open with more details.
