[Plugin: FancyBox Gallery] popup appears waayyyyy down below the post

I hope this bug is fixed, because I’d really love to use this plugin. But the popup doesn’t appear in front of me. Instead, I have to scroll the browser window waaayyyy dowwwwwn past the site footer, and there is the popup on a plain gray background.
