Global Menus don't work

[EliCoten]

After using LibreOffice for a little while, none of the menu options do anything.

All the menus are displayed, but when I click on any of them, nothing happens. I have tried a handful of commands from a handful of different menus, and none of them do anything.

I've tried:
File -> New -> Text Document
File -> Open
File -> Close
File -> Reload
File -> Print
Edit -> Paste
Edit -> Points
Edit -> Delete Slide
... and ...
Help -> Licensing Information
Help -> About
and none of these work

If I close down LibreOffice and open it again, the menus start working again.
