I just added

<?php comments_popup_script() // Uncomment to include javascript to open pop up windows ?>

to the head section of my phoenix installation's custom skin then grabbed _popup.php from phoenix's originalb2 skin and now have popup comments. Never actually did it before because I'm not into popup comments, but it seems to work for me.

One issue I noticed is that when you grab the popup.php file it'll call for the layoutb2.css file, which probably doesn't exist. Reckon one would want to do something about that eh?

I allowed javascripts from your site long enough to see that your popup code works on the second link, but I get a failure message telling me it can't find a file in the b2evocore folder. I'm thinking that means you're using an older version of _popup.php, or somehow have a mix of old-way and new-way. On your first link I don't see the popup script in the head section so that's a path to revisit.

Thanks for the prodding to take a fresh look!

Here's what I discovered: I'd been using direction from this posting http://b2evolution.net/man/2004/07/06/pop_up_howto along with a comment in that posting. There is direction to add a bit of javascript controls to the PHP comments_popup_script (this caused my problems) once I removed the 'extra stuff' my edited skin worked fine.

So now I have the comments_popup_script code you suggest and the _popup.php in that skins folder and all is good.

Add on Question:
It would be nice to be able to control the popup box (size, scroll bar, etc...) where is the proper place to implement those controls?

Thanks again!

It comes from the .9.0 documentation, but a quick cruise through the shiny new evocore folder shows me the params are still the same.
