I have as form with a tab control and a text box. The text box has a concatenated string pulling from the data source of the master form. The first picture is an example of the way the form should look. Here's the rub. When you click on the third page of tab control the data in the text box disappears. This is the only page that does that. You can see that in the second picture. Apparently this goes back many editions. I just noticed this today.
