Might be a communication problem but the answer to my question didn't make any sense to me. Lacking anything else and no further explanation I just experimented a bit when I had time. Solution seems to be just doing a one way synch on the gaining computer. Moving from A to B just be sure the BB is current then do a one way synch to B. Same on reverse. After than all seems to work fine.

The whole synch thing with BB is a kludge out of cave man times. Hopefully they will make some changes in the new system.
