Are you sure you use the anchordocking manager and not the easydockmgr?
The anchordocking has by default a drag threshold of 4 pixel. A simple
click on the header does not start the docking.
I can reproduce this here, with the anchor dock package. (didn't count
the pixels, 3 or 4....)
Just a click, it happens on mouse up.
IMO this misbehaviour results from the inappropriate setting of
DragImmediate=True, inherited from Delphi. This default does no harm
with drag-drop (no harmful action triggered), but is inappropriate for
drag-dock, resulting in an immediate undock. The LCL could distinguish
between the start of a drag-drop or drag-dock operation, or simply could
set the default to False (delayed start). Unfortunately my according
suggestions were rejected by the LCL developers :-(
That's why the EasyDockMgr sets DragImmediate=False, on installation.
