I noticed that the slideshow satellite is very very slow on google chrome.
If you go to this website http://www.johanvanwalbeeckschool.com/welkom-op-onze-website and scroll down to the slideshow you noticed it hangs and makes the page very very slow. Do you know what this could be? I don't have much plugins installed so not sure there could be conflict with other plugins.
I'm using the premium edition I bought one time!
