If you search in the support forum you will find several threads talking about the tab ordering. This problem is all about your configuration and your CSS properties. Obviously I can't control these aspects of your website. So, it is not an issue of my plugin at all.
Pros: Integration with reCAPTCHA, simple interface.
Disadvantages: if you do not use reCAPTCHA, you have problems with HTTPS.
Technical support - do not used.
Using CB reCaptcha for registration on the blog and the website of the university.
Engaged in web technologies since March 2007. Use Joomla since December 2009.
Easy to install and to set.
One little thing, I choose reCaptcha, because with cache enabled and myCaptcha the Captchaseems to be cached.
But that's not a real problem because setting reCaptcha is really easy too !
Thanks for this "must have" plugin for CB
If you use joomla cache plugin the image generated in myCaptcha mode will be cached. The plugin store the full html of the page for the next unregistered visitor.
Anyway, It's not a problem at all (from my point of view).
