Well, it did not work for all ships, yet Puke has found out what either caused it or perpetuated the problem:

1 I had individual ministers turned on for each ship (although only resupply and transports;
2 AI setting not to make changes during a simultaneous game was ticked, so if my ships did not move for some reason, the AI would perpetuate this.

Puke, who I sent the files to, mailed me that he was able to move the ships after he changed these two settings, so this problem should have been solved by now.

Thanks for all your input. This is a very helpful and friendly forum.
