The first Rownum is 1, I believe.

Then it looks as if the problem *might be* around the positioning of the
buffer cursor and the timing of your call to qryAdressen.Search. Can you
do a trace to check the value of the IncSearchKeyString at the time when
the unexpected behaviour occurs?

I'm reaching for things here, but maybe you need to call IncSearchKey
rather than IncSearchString, if you are passing only a single character to
the search. You can pass a Boolean Timeout argument to IncSearchKey. I
don't know if this is relevant to your case, because I can't tell from your
description whether each character-buttonclick is intended to create a
self-contained search argument or whether your code is designed to add a
character to the search argument on each character-buttonclick.
