The Carousel Includelet doesn't seem to move onto the next "slide" when loaded on a PC, but works perfectly on phones and tablets.
Can you give me a URL of where this seems to be happening, and details of the browser?
I had a look into this last night and couldn't quite reproduce the problem. I did find that sometimes it took longer than 20 seconds to move away from the first slide, but eventually it did move, and after that was pretty much bang on 20 seconds each time.
If you wait longer does it start moving?
Just run a dual test. I set off the page on an iPad and a PC at the same time. There are 7 slides. The page stayed on slide 1 on the PC whilst the iPad when through all 7 slides and then moved on to the 8th & 9th. The carousel did not move at all during this time on the PC.
