Go to demo.photo.gallery, and the slideshow should start in play-mode. Try to click the toggle-play button while in play-mode, and see what happens.
Is the button working properly, stopping the slideshow? Or does the button just blink, and the slideshow goes back into play mode? I am experiencing the latter issue from an old Windows-Vista computer using Internet Explorer. I would like to know if others are experiencing the same issue, or if it's something local.
If anyone happens to have other Windows-devices like Surface or Windows phone, would be cool if you could check from them also.
THNX!
