On my 2011 MacBook Air, if I bring my MacBook in from home, where it isn't plugged into any monitors or DisplayLinks, and plug it into my DisplayPort monitor as well as my DisplayLink monitor -- without opening the lid -- the MacBook will report that it has three monitors available: The DisplayPort, the DisplayLink, and the MacBook Air's internal screen.

If I reboot, the Air's internal screen no longer shows up, as expected.

Is this a bug in DisplayLink or in Mac OS (running 10.7.2)?
