Works for me. TM
What I'm thinking:
When you enable captcha do a hard reload/refresh on magra before posting. The page is cached in your browser and this way you get a fresh one form the server with the new settings.
There are a number of possibilities how to do this, all fugging browsers does it differently. Like Ctrl+F5, Shift+F5, Ctrl+Shift+R and probably others.
Could try Shift + Click Refresh.
