Hi,

>I'm not sure what was going on--very unusual. It was the only form in the sample application that displayed this behavior--and oddly enough, if you closed the form, rather than navigate to a new record, it did display the warning. I simply rebuilt the form, and it worked correctly--another Windows Forms mystery!

I have downloaded and installed the current msi. and, as you say, the behaviour has disappeared. However changes to any cells in the 'Order Detail' grid are not saved at all when I use the navigation buttons unless focus is first moved away from the cell (I don't know whether this was the same in the previous version).

On a related note: How do I (or you) determine exactly which version of an assembly I'm using since there is no build information in the versioning.

Regards,
Viv
