Now I remember that when I click with the mouse, the field isn't selected either - only when I enter with TAB. It seems to me you have or had custom code that provides this functionality (perhaps as part of a third-party framework), and now this custom code isn't available any more. Check if you didn't break inheritance. The most common way to break inheritance is to write custom code in some method and forget the DoDefault().
