Hi, Jim, I made the experience that the current OpenDCL palette state is stored in the "%appdata%\Autodesk\Autodesk AutoCAD Map 3D 2022\R24.1\deu\Support\Profiles\FixedProfile.aws" or in the "%appdata%\Autodesk\Autodesk AutoCAD Map 3D 2022\R24.1\deu\Support\Profiles\Map\Profile.aws" when AutoCAD is going to get closed. Since I do not use dockable bars, I cannot say if the states are also stores there or somewhere else (registry, cuix?). But I think a simple sample of three, four little forms could help to understand what is going on and what you are expecting to get.
Sure, not helpful for you now, but however interesting enough for reproduction and understanding.
With regards, Fred
