1.5 Beta reCaptcha collides with other captcha plugin

[phenry]

Hi Jan,
first thank you very much for the 1.5 beta. Works fine and I used the new security settings. So looking forward how it will work for me.
I enabled the reCaptcha function in the guestbook and found that I could not solve any captcha. When I disabled my joo recaptcha plugin then the guestbook work. Is there anything known with collisions or do I have to be aware about anything special with more than one captcha instance?
Thank you for any hint
Peter

Hi, in fact no idea, didn't and don't know about such possibility to be in conflict - but maybe there cannot be run both captchas on one site
