TDBAdvGrid

Hi

I useDelphi 10.2 and TDBAdvGrid (version 2.4.6.0).
This grid shows some records, which is fetched from a Firebird Database.

When I click in the lower end of the grid on a record, the entire result "moves".
Example:

I have these values:

1
2
3
4
5
6
7
8
9
10


For simplicity only 1-7 is visible.
I click on 6, the rows moves, and the selected row is now 9.

I cannot find the setting, thats does this.

Can anyone guide me?

Regards
Michael
I found the cause myself.

I had some code under OmKeyPress, which did this.
