                   switches a pane (i.e. several times for the same pane).
                   This does not happen with the tabs in Firefox, and while
                   trying to make it work with both at once, I was almost
                   going insane. This onload/onunload/okHandler stuff here is
                   extremely fragile. This version happens to work, I don't
                   know why, but I can't see it anymore, after fighting
                   with it for maybe 2 days in Communicatior and slmost
                   another day in Firefox, only on this
