Peter's Captcha not enforced

Hi,

I installed this package and for some reason Peter's antispam doesnt seems to be enforced, i get the image but i either type a wrong one or dont type anything at all, the comment is still accepted. I notice in the code that i should i get a message so something's not right.

The spam filter works perfectly fine and i havent tried the trackback but i guess it should be fine.

I also didnt see any admin menu, am i doing something wrong ?
