there is an strange issue with the LIghtbox. I linked it to a video (vimeo link) and each time I click on the lightbox the video opens twice with a 1 sec lag which makes it very annoying to watch.
Sample page with issues:
Issue appeared under
Chrome Version 45.0.2454.15 beta (64-bit)
MacBook Pro (Retina, 13-inch, Late 2012)
OS X Yosemite Version 10.10.3
Any ideas about that?
