I updated to LibreOffcie 5.1 from 5.0 and all the menus disappeared. There was no apparent way to get them back or use any part of the interface except for the toolbar. There was only a black space where the menus should have been.
Windows 7 Prof. 32GB RAM.
I temporarily uninstalled and reinstalled version 5.0 to solve the issue. Is this a known issue or is there a workaround?
