  10. The following code, was extracted from the case WM_COMMAND section
  11. of the dialog box. When moving from one edit control to another with both
  12. fields being empty a EN_KILLFOCUS is sent to both edit controls.
  13.  
  14. Could someone please help me change the following code so that a
  15. EN_KILLFOCUS message is sent to the leaving field.
  16.  
  17. I have been able to determine that it looks like the MessageBox is causing
  18. a EN_KILLFOCUS message to be sent to the target field.
