This is by design. Dockable forms are AlwaysOnTop = .T.

>2. At opening the form in the designer methods of the form and the enclosed controls in Document View window are not shown

I think this is also by design. When you open a code window, the DocumentView becomes populated. The same behavior also exists when Dockable = 0.
