Moving mockup folder's effect on starting Balsamiq: many "New Mockups"

Open several mockups. Save the mockups. Close the window. Move the mockups you had opened to a new folder. Open balsamiq again. You'll have a bunch of "New Mockups". I suppose the expected behavior would be just not to open so many new mockups. In my situation, I had 10+ mockups going, finished working, moved the folder to organize my desktop, opened to find 10+ new mockups. :P
