It looks like after opening the drop-down list, some kind of "autocomplete" is triggered and the control searches all items for a match to the text and then replaces it.

Any idea how to deactivate the auto-complete feature?
The MS control behaves the same. This "feature" can be deactivated by only blocking LB_FINDSTRING and returning -1.
