'Show changes in output' doesn't work

[Zohar]

Hi,

I turned on the track changes, and I can see the changes tracking in the editor,
and when I click 'Show changes in output' the changes are still shown. I would
like lyx to track my changes without showing them to me (and clatter the 
editor).

What am I missing?

I use lyx 2.0.4.

Thanks
