Docking toolbars in custom order

Hi all,

When I dock a toolbar to the top, for example row 2, position 3,
reading the toolbars' left, top and dockstatus properties yields
left=2, top=1 and dockstatus=0 (acToolbarDockTop). This perfectly makes
sense assuming the left and top properties define the toolbar position
in the "2-dimensional toolbar-array" in this case. On application
unload, I save the left, top, dockstatus values of the toolbar to the
registry. When I load my application in the next AutoCAD session, I
assign these saved values to the toolbar:

m_pMyToolbar->put_Left(left);
m_pMyToolbar->put_Top(top);
m_pMyToolbar->put_DockStatus(dockstatus);

However, put_DockStatus() seems to reset the left and top values to 0
(reading left and top after put_DockStatus() yields left=0, top=0) and
dock the toolbar to the top-leftmost corner. This behaviour is true for
each DockStatus except floating (which works perfectly fine).
Ideas or workarounds anyone? Or is it a (more or less unsolicited)
customization restriction?

Thanks in advance!
