The same thing occurs with a vanilla combobox. There's no

Hmm.. Selecting a line with MasterId 2, highlights "eeee"
correctly. A
miracle? No, TDBLookupComboBox.DataChange does a
FLookup.GetKeyIndex
and updates the combobox. FLookup.GetKeyIndex does a simple
"run over
Flookup and stops on first match". So, yes it can be changed.
Please, send a patch.

Did some further testing. The combobox gets the correct index but the
combobox repositions the selection as soon as the dropdownbox is opened and
the value is copied to the edit control. So windows starts the "update
selection as you type" immediately. Looks like this is also intended to work
on sorted strings because when you have a 'xxxx' on the top of the list and
a 'xxx' on the bottom, you'll never get to the 'xxx' by typing the letters.
A workaround to this is to use csDropDownList. The value is displayed in a
text control instead of an edit control and the selection stays when opening
the dropdownbox. Downside is that keyboard selection only works on the first
character.
The same tests (and conclusions) i did.
Not very much that can be done about that...
As i said before ;-)
