We just updated our project to the latest release, and i have now seen in multiple forms that where I use a TAdvColumnGrid with a TColumnComboBox as a custom editor, when the combo drops down, it immediately drops up again, preventing selection from the list. Worse, I see the value from it written to the cell in the row above the row where the combo was opened.
This is a problem urgently in need of solution, as I have many instances of this model in a very large application.
