Len,
I've had this happen too sometimes. You must allow all four phases of annealing to finish completely, and have the program return to back-prop on its own. Whatever you do, don't interrupt simulated annealing training pass 4. Let it finish on its own. At 40 neurons, it takes hours and hours. At 60, I don't know. If something interrupts 4, when you start to train again, go to options and turn off back-prop and start it training with annealing. After you started it training, then go back to options and turn back-prop back on. Once you get to training cycle 40000, you should see the line starting to converge again in the stats window and all the scattered dots should be disappearing.
By the way, concerning the net that I set to you the other day, I have continued training it and now have about 75 hours on it. With the additional training it has become extremely tight and now looks great.
Good luck and have patience.
