Gene, give this a try. Go into the app data folder and delete the buttons.xml file. Then try starting the program again. It should start in edit mode then. I've found XP to be a bit of a conundrum to get the program to start in edit mode again (after setting production mode) by holding the shift key. The way around this is to just edit the buttons.xml file by right click and edit and change the line <Run>1</Run> to <Run>0</Run>. Then, it will open in edit mode next time.
