Does anyone have any ideas on how this is happening? We are trying to save the docking panes into a string to put on a db... and then using the LoadSaveFormString but it adds both pictureboxes to one pane. There should be two panes one on the right and left side. 

The code we are using is this:

With Me.DockingPaneManager
        .VisualTheme = ThemeExplorer
        .Options.CaptionDirection = PaneCaptionHorizontal
        .Options.LockSplitters = True
        .PaintManager.SplitterSize = 2
        .PanelPaintManager.Appearance = xtpTabAppearanceFlat
        .PanelPaintManager.Layout = xtpTabLayoutFixed

        Set PaneOptions = .CreatePane(ID_PANE_OPTIONS, 241, Int(Me.Height / 15), DockLeftOf)
        With PaneOptions
             .Title = "Search Options..."
             .MaxTrackSize.Width = 241
             .Options = PaneNoFloatable Or PaneNoDockable
        End With

        Set PaneFields = .CreatePane(ID_PANE_FIELDS, 115, Int(Me.Height / 15), DockRightOf)
        With PaneFields
             .Title = "Field Chooser"
             .MaxTrackSize.Width = 115
             .Closed = True
             .Options = PaneNoFloatable Or PaneNoDockable
        End With

             Set rs = objWOODLOCH.sel_codejock(curuser.lUserid, Me.Name, .Name)
             If rs.RecordCount > 0 Then .LoadStateFromString (rs.Fields("s_config"))
             rs.Close
    End With

but if we comment out the last lines about setting string to the DB we get the orignial

Are you sure ID_PANE_OPTIONS not equal ID_PANE_FIELDS?

Use debug.Print to check if this constants are different.

I see

.Closed = True
.Options = PaneNoFloatable Or PaneNoDockable

may be these lines problem. because pane must be or PaneNoFloatable  or PaneNoDockable. try to comment them.
