I'm using mobile tools on a drupal 6.24 site along with the CAPTCHA 6.24 module. For some reason on the mobile site the blog's comment form appears fine but it will not show the captcha challenge, so it will not allow mobile users to post comments. I tried to set the anonymous user (Mobile) to have the 'skip CAPTCHA' permission but it doesn't seem to work unless the anonymous user has the same permission. I was hoping that I could get the permission to work properly allowing anonymous user (Mobile) to skip the CAPTCHA challenge.

I checked the user role that is given when a mobile visitors and it is the correct role but it seems that the user_access it give is that of the regular anonymous users.

I'm not sure how I could fix this but if anyone has any ideas please let me know.
