Hi Ciaran,
I am experiencing an issue on both Juliet and Chloe templates. As soon as I change an image in the Layer Slideshow module, the whole module shifts upwards and the image is also shown behind the menu. In Chloe even the menu shifts upwards as well.
After this kept happening in Chloe, I decided to download Juliet and start over. I cannot show you what happened in Chloe, but attached a screenshot of what happens in Juliet.
