All I can say is it works for me. Do you have some other code that could affect it? Try this:

PUBLIC oform1

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


	**************************************************
*-- Form:         form1 (c:\vfp9stuff\incsearch.scx)

DEFINE CLASS form1 AS form


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


	ADD OBJECT combo1 AS combobox WITH ;
		RowSourceType = 2, ;
		RowSource = "incsearch", ;
		Height = 37, ;
		IncrementalSearch = .T., ;
		Left = 108, ;

		Name = "Combo1"


	PROCEDURE Load
		CREATE CURSOR incsearch (f1 c(10))

	ENDPROC


ENDDEFINE

I tried this with both VFP6 and VFP9 beta, and I didn't even have to mess with either of the system variables to make it work.
