David,

I need to have more detailed information to be able to track this down or see the data myself.

Can you tell me exactly what they are doing when they receive the error? Does it occur immediately after they click on the Adjustments button in the toolbar and the grid displays? Or, after they do the same from the Transactions menu? Or, is it right after they click New or or enter information into a field on the Adjustment window?

Let me know.
