Thanks for the suggestion. This is what I eventually settled on, although since this is a laptop I end up changing the display configuration fairly frequently. I use "disper" (http://willem.engen.nl/projects/disper/
) and I just have to make sure I specify the top monitor first so that it is the primary. This works out great at home, but at work I really would prefer to have my laptop be the primary monitor for a variety of reasons. The work-around is acceptable, but not ideal.
