Terminal windows not listed in switcher

It appears to me as if unity doesn't really see Terminal windows. The Alt+Tab application switcher doesn't list them at all. And after I've dragged the Terminal icon from the dash thingy to the dock, it still isn't illuminated like other running applications are, althigh I have at least three terminal windows open. It appears that the Terminal I'm using is actually gnome-terminal.
