Tracy,

Slight correction, since it struck <g> me:

5 - is optimistic, 4 is pessimistic <g>

>What is the rowsource of the combobox? How is it created?

>Just some stuff to rule out. Is multilocks on? Is the cursor buffering mode set to optimistic table? What does dbf() return on the cursor you create? Cursors usually are stored in the tmpfiles location. What happens if you set multilocks on and set the buffering?

>IF SET('MULTILOCKS')<>"ON"
>	SET MULTILOCKS ON
>ENDIF
>CREATE CURSOR mycursor (cfieldname c(30)) && whatever your cursor is
>? DBF('mycursor') && this points to my tmpfiles location set in config.fpw
>=CURSORSETPROP("Buffering", 4, "mycursor")  && optimistic table
>*Now try selecting from the combobox
