[Plugin: SI CAPTCHA Anti-Spam] si captcha and proloue theme fix?

Does anyone have a fix for using SI captcha with the prologue theme?
I noticed that prologue theme does not have the necessary
“do_action(‘comment_form’…etc” fo SI captcha to function properly.

I have SI captcha set to hide capcha for registerd uers, but when a registered user visits the sub blog running prologue theme, when they leave a comment and hit submit, an error page shows something like
“you did not enter a captcha phrase”

I am guessing that code needs to be added to prologue somehow, but not sure if it will break prologue, or if it needs to be done in a certain place for it to work – or if it will ruin the ajax functionality of prologue or whatever.

any help certainly appreciated.. WP 3.05 multi-site, sub blog, SI captcha network activated, with buddypress and a few other plugins. Prologue theme issue I think.
