The program works exactly as advertised, and always impresses my Windows-using colleagues when I hook the Mac up to a projector for a conference room briefing and display my desktop. The author is also very responsive. After getting my MacBook, I realized that the map did not scale properly with the new screen dimensions. The author replied to my email and sent me an update in fairly short order so I could test it on my laptop. The update worked perfectly. I'm not sure why it hasn't appeared here, but I'm now running version 3.0.4, which supports the 13-inch MacBook screen.
