When multiple carousel sliders are on multiple fullscreen slides and one uses the arrow keys to slide left and right in the carousel sliders, the slide happens on supposedly every carousel slider on the fullscreen slider page. So when you, say, slide from 1 / 5 to 2 / 5 and then move to another fullscreen slider view with another carousel slider also this slider has moved form 1 / n to 2 / n.
Minor Bug: Fullscreen slider + arrow keys
Good to know thanks for pointing this out.
Will forward this -
I believe Armin already has your login detail if necessary from the next thread,
I'm releasing a carousel udpate now.
If you update your carousel addon, this should be fixed!
