When the code below is run under VFP 6, the first character typed into the combobox doesn't change its DisplayValue property. After typing another, DisplayValue starts returning correct values. The same code behaves correctly in VFP 3 (DisplayValue returns the first character typed).

oForm = CREATEOBJECT("Form")
oForm.Autocenter = .T.
oForm.Addobject('combo','_combobox')
oForm.combo.Visible = .T.

oForm.Show()
