TIB_ComboBox is based on the Windows API combobox. As such it is
forced to operate in that manner. There are many other
inconsistencies with the API combobox (control sizing problems,
incremental search only operates with one character etc). You could
try adding a blank option to the Items.
If you want a combobox control that is more flexible and consistent
(all IMHO of course :-) then try out my enhanced components.
TIB_ComboBoxEnh is based on my CustomEditEnh class and does not use
the windows API combobox at all.
