Thanks for the information Tracy.

Are you aware if the problem occured prior to using version 8.1E?

Could you be a little more specific what you mean by 'going in and out of the vendors box'? If you could indicate something like 'I edit a vendor, and when I click the OK button to save changes I get the error', or similar detail in the steps to cause the problem.

Sample data would have been installed in the \softrak\apwin\samdata directory.

You might have a new computer, but I presume that you are using Adagio on a network, thus the transfer of data across the network could also be a choke point.
