Why cannot my forms/subforms become moveable

I am trying to redesign my database (Access365). I want all my forms and subforms to be moveable, but when I try to change the moveable option in the property sheet into "Yes" it is not accepted. I have tried to find some general options for my database, but found none. I hav no code. Biorn Veiro

Answer

If you have tabbed windows, you must first change to floating windows with this command:

SetDbProp "UseMDIMode", 2, 1 'dbByte=2. Overlapping windows.

This is an application wide setting, while the Moveable property is per Form.
