Jörg,

Why do you want to change the ShowWIndow property?
This property is for setting the form: 0 as In Screen, 1 for In Top Level Form and 2 for As Top Level Form.
Not for activating the docking facility.

For activating the docking facility you have the property Dockable, with 0 for no docking support, 1 for supporting docking and dockable, 2 for supporting docking and not dockable.
I suppose you are after 1

Regards,

Koen
