After messing around with it and basically getting nowhere on this problem, I just completely uninstalled LO4.0 and went through the alternative offline install procedure on LO365_32bit. All is well now. I'll wait for the next rev of LO before I try it again.
That's great that you finally got it fixed.
I wouldn't say it's fixed yet. I just reverted to the previous revision of LO (3.6.5).
Just got the LO manager update (V4.0.1) and installed LO. Menus are now fine! I will mark this as SOLVED.
