I have two 27" Thunderbolt Displays (daisy-chained) plugged into a 15" MBP. The problem is, seemingly at random, the monitor's switch arrangement, the left being primary one day, the right another day. I haven't been able to find any sort of pattern in the switching.

 

Also, if it helps clarity the problem, my MBP is always closed when I plug in the monitors.

 

Is this a bug? Any workarounds?

Same problem here. I'll (we should) file a bug report to Apple. I'm guessing that Lion is not patient enough to wait before getting all of the TB monitors conected on a list before (re)assigning them to the previously defined arrangement. This really spoils the whole experience when you have to fix your arrangement with each move between work places.

 

Also, the desktop background image is lost when this happens. Arrrgh!
