Eric,

Here's more questions, not answers, but they may give you some ideas.

1. Have you checked the Unique IDs to make sure that each user is adding a different value?

2. Does this happen with all 3 tables?

3. Does it happen if you switch the child tables to Optimistic (or even Pessimistic) row buffering?

4. Can you reproduce the problem on demand? If so, have you walked through the code with DEBUG watching your record #s?

5. Could it be related to the REFRESH value? What is its setting?
