WordPress 3.5.1 and Nextgen 1.9.12 versions and the standard visual editor on a Linux server.
The client is a Macbook Pro with OSX 10.8.3 (the latest version of the OS) and Chrome, Firefox and Safari browsers.
Everything seems to work fine with Nextgen, I can can create galleries, upload photos and show them.
Problem: When I use the visual editor to create a post or a page and click on the Nextgen icon the popup never shows and instead there is an ugly addition to the bottom of the page that I have to scroll down to for adding photos and slideshows to the post or page?
I have also tried another computer form and get the same result and that makes me assume that it is some server or WP or NextGen settings but I am not able to find it……
