Comment 1 for bug 870091

I think the "Keep on top" step is unnecessary for this to happen. My daily workflow involves:

 - irssi in a terminal window on a second monitor, snapped to the left.
 - ssh into a virtual machine on my main laptop screen, maximised
 - Firefox on my main laptop screen, maximised

I frequently alt-tab between the SSH session and Firefox and back and start typing code or build commands into irssi. Unity just doesn't seem to remember which of the terminal windows I used last.
