For those using GeoBeagle, I highly recommend you go to the project download page (http://code.google.com/p/geobeagle/downloads/list) and get a more current version than the market. These devs are doing some amazing things, including some powerful list filtering, offline logging and "favorites", new graphics and a lot more. They're working hard on getting things together for a market release, but I've found the 1.4.1 version to be very stable, even with a huge GPX file imported.
