Thanks for Your Answer Fabian.

Unfortunately is not working.

The Settings I changed for the forms are:

AutoCenter: .T.
BorderStyle: 1-Fixed Single
Caption
Datasession: 2-Private Data Session
Font Size: 8
Height, Icon
MaxButton : .F.
Name
Showtips: .T.
Width

The Maximize Button remains enabled although MaxButton = .F.
Also, If we Double Click at the caption area of the form it gets maximized.

We want to disable this behaviour.
