I saw a similar problem when I was juggling around cards in my display
machine. I managed to get it back to the right place by disabling all
of the outputs except for screen 1 (the first output on the AGP G450)
and rebooting. The taskbar reappeared on that screen, and then I could
go back and add the other outputs back into the mix. I don't know if
this is what you mean by switching displays around; if so, I think
that's a big cry for help from our Microsoft friends!
Good luck!!!
