audacity scrambling desktops

[rikona]

I've been trying to edit a couple of mp3s with audacity - 12.04
Ubuntu, updated. Every time I try to save an edited file, close
audacity, etc, it scrambles all the desktops. **Every** window gets
sent to a different desktop in what seems to be a random way. Also,
since that started, if i try to minimize or change a window, it also
gets sent to another desktop, but not minimized. Anybody else seen
this? Any idea what happened? Most important, how might I get this to
stop?

So far, only happens with audacity, and the window errors continue
even after audacity is closed. Is the old Windows reboot the answer?
