Hi all,

I encounter a very strange problem on a machine where all used to work fine.

It runs Windows 10 latest update and NVDA 2018.1.

In Mozilla apps, (thunderbird, Firefox) any object is announced as "unknown".

More generally, in any app, conext menus are nomore spoken.

I triend to uninstall and reinstall NVDA, even deleting the NVDA configuration directory, but it definitely does not work.

Has anyone encountered this and know how to fix it ?
