Lightbox not working in newest version of wordpress

I have just installed this on three sites.

Two were on WP 3.5
It worked on one, but not the other.

Eventually I found a compatibility problem with another plugin Lightbox2.

It worked OK on my 3.6 install too.

Looking for a solution to this as well. Instead of it showing the progression loop, it’s showing the home page on the second click. any help?????

My first problem was that the cursor went to the top of the page on the 2nd click, but disabling the lightbox 2 plugin fixed it.

I just noticed that my test one, linked above, does not work on the 2nd click, even after deactivating the Lightbox Plus ColorBox that is on that site.

I think it may still be another plugin conflict though. Just no idea which now.

Easy Fancybox is a working alternative, but does not work with multi-page forms.

…actually it does with ajax enabled
