About rhino 5 x64 toolbar position?

I set the toolbar to a any position of menu area, but it reset the default position on every open Rhino program, why? any idea?

If it were me, I’d start Rhino with elevated Administrator rights, by right-mouse clicking on the Desktop icon and using Run as Administrator.
Move your tool bars again, then close Rhino.
Start normally (not as Administrator) see if they are fixed.

Any luck?
