Okay. Thanks Raapys! I now remember encountering these but not the "Stuck Tech". I always thought that the ships appearing and disappearing as they maneuvered was do to the opposing electronic systems battling each other. I agree that it was very annoing.
I will now install the Vanilla upgrade because looking again at the list I see that they are all reasonable and some were very needed or wanted.

As for the artificial intelligence in Master of Orion III, I played on "Hard" level(the third out of four) and remember the AI using war, espionage, diplomacy, and research well.
