Hi John - the time expander idea was just a thought on my part, since Mbot was having so many crashes...on the order of, "If A doesn't work, try B; if B doesn't work try C, etc." I appreciate that you made the program and truly meant no insult to your work! Sounds as if your assessment must be the bottomline - luck.

On a history note...I remember reading that the Navy had a huge complaint about how realistic looking the screens were.

Realistic as what you see in the movies or realistic in a "real" sense ?
As a note, I would really have liked to have that kind of realism in DW, incoming messages formatted correctly, and all those details....

In the real sense...I was shocked at seeing the sonar screens.

It shows that the lead designer of Fast Attack was a 688(I) skipper :)

sonar732, would you think that such screens, perhaps with even bigger realism, would still be a problem today? These seems to be outdated systems, on current photos the sonar stations of LA subs look quite different.
