Thanks, but not related. My problem has something to do with the Combobox Visual Refresh. (It's true its Comboboxes and not Listboxes - my fault)
I post the repro code below (just paste the code into a .PRG and run it):

oForm = CreateObject("f2")
oform.Show(1)

**************************************************
*-- Class:        f2 (k:\f2.vcx)
*-- ParentClass:  form
*-- BaseClass:    form
*-- Time Stamp:   10/23/06 10:12:11 AM

DEFINE CLASS f2 AS form


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


	ADD OBJECT combo1 AS combobox WITH ;
		Height = 24, ;
		Left = 48, ;
		Top = 60, ;
		Width = 180, ;
		Name = "Combo1"


	ADD OBJECT combo2 AS combobox WITH ;
		ControlSource = "x1.rsource", ;
		Height = 24, ;
		Left = 48, ;
		Top = 96, ;
		Width = 180, ;
		Name = "Combo2"


	ADD OBJECT combo3 AS combobox WITH ;
		RowSourceType = 1, ;
		RowSource = "A,b,c", ;
		ControlSource = "x1.rsource", ;
		Height = 24, ;
		Left = 48, ;
		Top = 133, ;
		Width = 180, ;
		Name = "Combo3"


	PROCEDURE Load
		IF USED("x1")
			SELECT x1
			USE
		endif
		create CURSOr x1 ( rsource c(30))
		SELECT x1
		append blank
	ENDPROC


	PROCEDURE Init
		FOR f=1 TO 100 
		thisform.combo1.AddItem("i"+STR(f))
		thisform.combo2.AddItem("i"+STR(f))
		NEXT f
	ENDPROC


ENDDEFINE
