what you can do is:
If a pane will not dock, right-click anywhere in the border of the pane and ensure that Allow Docking is selected.
(recommend use the border at left, bottom, or right of the pane for the right-click, as top is for the move)
The one can dock again.
Start > Programs > Autodesk > Autodesk Moldflow Insight 2011 > Autodesk Moldflow Insight 2011 Command Shell
This will reset personal settings and parameters, and the menus will be docked when starting Synergy.
