Problem with Apple Safari desktop and iPhones. It takes three clicks on the continue button to get past the intro on a survey when the questions are done by groups. No problem if all the questions are on a single page.
I have tried all of the themes with the same results. I have also installed LS on two different servers with the same results.
The "Disable Ajax Mode" does not seem to exist on the version I am using if that was an option.
