Tony,

>On one of my forms, which has a lot of mmTxtBox's on it, there is a mmPicker button which I use to pick a vendor. It fills up a number of those txtBoxes values with vendor data. However, the table underneath those txtBoxes does not get updated when the form is saved.

>Refreshing the form in any way does not work.

Are you manually setting the values of these text boxes when an item is selected in the picker? If so, check out the MM .NET Dev Guide topic "How do I programmatically set the value of Windows Controls?". Otherwise, there is a change in MM .NET 2.2 that may help you out (you should receive an e-mail tomorrow with download instructions).

Best Regards,
