>when I look at the listbox the "pointer" doesn't move, I then hit the up or down arrow and it puts me back at the top of the listbox

Hmmm, well, what is the record source of you're List Box? What is the control source? You can simply update the field the control is bound too, and refresh() it.

Here's is what I was doing in my first example:

oForm = createobject('listsearch')
oForm.Show(1)
DEFINE CLASS listsearch AS form


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


	ADD OBJECT list1 AS listbox WITH ;
		RowSourceType = 1, ;
		RowSource = "a,b,c,d,e,f,g,h", ;
		Height = 170, ;
		Left = 60, ;
		Top = 60, ;
		Width = 240, ;
		Name = "List1"


	ADD OBJECT text1 AS textbox WITH ;
		Height = 23, ;
		Left = 60, ;
		Top = 12, ;
		Width = 240, ;
		Name = "Text1"


	PROCEDURE text1.KeyPress
		LPARAMETERS nKeyCode, nShiftAltCtrl
		if nKeyCode = 13
			thisform.list1.value = this.value
			if thisform.list1.listindex = 0
				messagebox('Value not found')
			endif
		endif
	ENDPROC
