Using LibreOffice Writer 3.4.1 under Windows 7:
While working on a document, the keyboard will suddenly switch to a French
keyboard configuration. The only option we have been able to find to switch back
to English is to shut down all LibreOffice windows and close all documents.
This has been marked solved in the forum:

However, we’ve tried that, and it doesn’t work in our case. Whenever we have
looked at it, it always shows “US English” even though the keyboard is operating
in French in LibreOffice Writer. (Other programs do not appear to be affected.)
