Rhino toolbar saving / error message at shut down

Hey there,
since a few days rhino does not save toolbars. The properties window always appears below the toolbars and not on the side where I put it again and again.
Tried to save files, also tried to save a template and reopen that.

System is Rhino 5.0, 64bit, Windows 7.
Just installed the update SR8, but still the same.

There has been an error message a few days, which was caused by the bricsys plug in.
I just uninstalled the plug in, restarted the computer. The error message is gone.
What stays is the denial of rhino to save the toolbar layout.

Can someone help, please?


Yes, I have seen the same thing on all computers I use since Rhino 5 came out.
I have to start Rhino by right-clicking on the icon and select “Run as administrator” (“Exécuter en tant qu’administrateur”). Then the changes to the workspace will be saved and show next time.
