I would send him another note, Barbara.
I found that I needed to -re-boot-, everything dulicmer, each time I made changes to my side of it...wonder if that will help?
Barbara, don't give up on ED. Bruce, these days, is CEO and Development Officer of a small R&D company developing scientific robotic submersibles and may literally be "at sea". When he was in the Navy it wasn't such a big deal as naval ships keep pretty good touch with shore electronically these days.
