I've used JB for a slider on the frontpage of my website www.huwelijkfotografie.nl. Loading goes fine, but when clicking on "Info" or "Welkom" which is the same page drops the images outside the div. In Safari (Yosemite v8.0.2) this only happens when clicking on "Welkom", "Info" works fine. In Google Chrome both don't work, only refreshing the page works. It isn't constant, It seems to do this randomly.
Also the image transition is set on "CROSS_FADE". This works fine on my iMac, but doesn't work on iPhone 5 or iPad 3 (both IOS 8.1.2). There it reverts to a slide.
Did I do anything wrong, or is this something within JB?
