This next part if largely for my own notes. After removing Tomtom from Leaves I now get an error - couldn't start TTGPSENG.EXE which was trying to be started everytime it got woken up. Getting dbView helped me track it down. The reference to it wasn't in the registry or any link I could find. It turns out in the DB_notify_events database. Using dbView I could delete the item. one annoyance down, several to go.
