I think something is wrong with preloader
On http://www.yoocare.net running this to override Enrico function:
window.removeOverflow = function() { };
And blocking dmxAppConnect/dmxPreloader/dmxPreloader.js
Seems to be working and no more freezing.
(Previously removing application - cookies - accept: Y in order to see modal again and again)
Tested a few times, and unblocking freezes the page again.
