Captcha Join Error using Chrome

Has anyone else had a problem with joining their site and using Chrome?

ive had some beta 2 sites i had to re install more then once to get captcha working.  Also when you click join it gives the little red error even though everything is filled out...  

I don't use the captcha. I got way too many spam bots. I have used another human verification method for Dolphin 7.0.9 with complete success in preventing bots from joining. I learned it from a programer on the DevelopPhp web site.  In the join form create a field that has a max value of 0 (zero).  Then set the defaullt value as "Delete this text"  Your caption can also instruct the user to delete the text in the box.  For some reason bots will not complete this correctly.  You will also want a Maximum exceed error message like "You did not delete the text in this box."

I have not yet tried splitting the form into two or more pages.
