Thanks. It is Build 415.
The error is still occuring. It comes up as "Cannot access table", and gives the error number as 1152. I have closed a number of temporary cursors that were open to see if that would stop it, but is doesn't seem to have helped.

>>I'm not sure, Nancy. I have updated with service pack 3 in February 98. In the 'About' dialog box, it just says '5.0a', but in the product id code there is a sequence -414-, so I guess that might mean it's build 414? Where do I find the build number?
