Hello, I've had a problem with Lightbox on desktop for the past few weeks. When clicking thru, it will skip ahead by multiple images. I have deactivated/activated all my plugins and everything is up-to-date. The problem can be reproduced at http://dev.susanweil.com/recent-works/
I will forward this to Armin for further inspection.
In the meantime thank you for your patience with this problem and for using Lay Theme.
Letting us know of bugs like this helps to make it better for others as well.
I don't answer or check forum DMs, please just post on the forum.
