As the user adjusts the bottom 6 fields, the repeat exposures are updated to reflect the total of all the repeat reasons.

As the Repeat exposures field is updated, the # Exposures field is updated to Repeats plus a base exposure (based on other settings on the form).

These updates are performed using a common event handler:

private void nudAllRepeats_ValueChanged(object sender, EventArgs e)
{
  txtRepeatExposures.Text = Convert.ToString(nudEquipment.Value + nudMotion.Value + nudOther.Value + nudPosition.Value + nudTooDark.Value + nudTooLight.Value);
}

If i make changes to any of the repeat reasons and click the save button on the toolbar, the record is saved, but the form stays in Edit mode (the Save and Undo buttons remain enabled). If I click Save (or Undo) the form goes the proper state of Idle.

I've trapped the AfterSave event of the primary BO and checked all the other BOs on the form to see if their state is in edit mode, but all are idle.

Any ideas on why this is happening?
