In answer to question #3....For the program closing issue, I use AE button Plus and assigned the "OK" key to a little program call "Zapit". A copy of Zapit is located at PDAphonehome.com. As an alternative button mapper "Double Launcher" can be used. All info and apps are linked below....

Double Launcher has the ability to work with one button for free and is $9.95 otherwise.
