Thank you for your response;
Yes I do.

* Init() has:
this.dField = 'vProd.Due_Date1'
this.InitDate = DATE()
DateSpinner::Init()
this.Parent.lblDow1.Refresh()

* Gotfocus() has:
this.BackColor = p_bcs
DODEFAULT()
thisForm.lblHome.Visible = .T.
thisForm.lblHome.Refresh()

* InterActiveChange() has:
DateSpinner::InterActiveChange()
this.Parent.lblDow1.Refresh()

* LostFocus() has:
this.BackColor = p_bc
DateSpinner::LostFocus()
IF this.Parent.SpDue2.dDate < this.dDate
   this.Parent.SpDue2.dDate = this.dDate
   this.Parent.SpDue2.Refresh()
ENDIF   
DODEFAULT()
thisForm.lblHome.Visible = .F.
thisForm.lblHome.Refresh()

Valid() has:
IF DateSpinner::Valid()
   this.Parent.lblDow1.Refresh()
   IF vProd.Due_Date1 # this.dDate
      SELECT vProd
      REPLACE vProd.Due_Date1 WITH this.dDate
   ENDIF   
   RETURN .T.
ENDIF   

* Refresh() has:
this.Enabled = thisForm.lAllowEdits .OR. thisform.HotLink
DateSpinner::Refresh()
this.Parent.lblDow1.Refresh()

Thanks.
