I just upgraded to windows 7 and took the opportunity to "upgrade" my Object Dock to 2.0 and I'm a bit frustrated at the lack of a few features I counted on.
First, it is apparently impossible for you to tell OD NOT to consider docks as drawers. In prior versions, it had the annoying default behavior to reset the "make dock a drawer" property every time you attached and unattached a dock from the side of the screen, but now it just does it and you can't turn it off?
I can make my dock "Floating" which sort of solves the problem of disappearing, but then the tabs move to the top of the window and there's NO WAY to tell it to have the tabs at the bottom.
I truly hate having my tabbed docks disappearing every time I click somewhere else and removing functionality to make the new version work like the developer likes is completely unacceptable.
