I am running AMD64 dapper and have the same problem, but it worked fine in 1386 Breezy for me, so it seems to be an amd64 bug.
there seems to be a similar bug listed in the openbox bug reports as well (from Hoary amd64): https://bugzilla.icculus.org/show_bug.cgi?id=2302 -- windows do not appear in gnome-panel workspace switcher https://launchpad.net/bugs/2415 -- universe-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/universe-bugs
