Ha. Well, it seems that the Preview version of the site is the issue. I published the site and now the issue is completely gone. I can open one of the gallery images into a lightbox window and it when it closes the site stays exactly where it was. That was several hours of fighting an issue that wasn’t there! Here is the site, feel free to look at it and let me know if the lightbox works for you like it’s working for me. Thanks for the help as well!
PS: The site isn’t complete, just getting the bones set up right now.
