>I didn't state my problem clearly. Nothing drops down when I click the down arrow on the box. It acts as if the list were empty.

Can you modify following test code to demonstarte your problem? It works for me.

PUBLIC oform1

oform1=NEWOBJECT("form1")
oform1.Show
RETURN

DEFINE CLASS form1 AS form

	DoCreate = .T.
	Caption = "Form1"
	Name = "Form1"

	ADD OBJECT combo1 AS combobox WITH ;
		Height = 24, ;
		Left = 67, ;
		Top = 84, ;
		Width = 240, ;
		Name = "Combo1"

	ADD OBJECT command1 AS commandbutton WITH ;
		Top = 180, ;
		Left = 145, ;
		Height = 27, ;
		Width = 84, ;
		Caption = "Exit", ;
		Name = "Command1"

	PROCEDURE combo1.Init
		This.AddItem("One")
		This.AddItem("Two")
		This.AddItem("Three")
	ENDPROC

	PROCEDURE command1.Click
		Thisform.Release()
	ENDPROC

ENDDEFINE
