I had a form with one table in the DE, some text boxes, and some nav buttons. No problem. I added a grid with .Recordsource = myview, and added the view to the DE. Still no problem. Then I added another table to the DE, intending to use it as a combo.Rowsource. Then my nav buttons stopped working. It would jump from the first to the last record, showing maybe one or two records in between. The behavior is the same, whether I use the form wizard buttons or my own nav buttons, which are similar. Tests with the debugger have indicated that the selected ALIAS() is shifting, and that the original alias, when it returns, is at EOF(). But I have no code that selects this third cursor in the DE.
