We've implemented fancybox iframe popups throughout our system and it works great, but I've noticed these annoying horizontal scrollbars popping out on the outside of the frame. We get scrollbars where necesary inside our content area, but these ones just show up 100% of the time even when there's nothing to scroll. I've tried a number of things with CSS but have not had any luck thus far. Screenshot below to show what I'm referring to.
Any ideas?
