[orca-list] Focus bug switching to Firefox

[Bill Cox <waywardgeek gmail com>]

In Ubuntu Lucid, and in Vinux, when I Alt+Tab to Firefox from a
gnome-terminal, the focus fails to set properly to Firefox.  When I
ran orca from a terminal in Ubuntu Lucid, I saw the following error
reported when I switched to Firefox:

vinux vinux-laptop:~$ orca
kill: 42: Operation not permitted

kill: 207: Operation not permitted

I suspect this has something to do with the bug.  Any ideas?

Thanks,
