That's very weird... Your cap doesn't run on here either, but others do. Perhaps you're doing something differently.
Edit: This is definitely behaving differently to the way the problem I reported did.
Edit 2: I may have worked it out. The boxes seem to be clipping out of the layout. I'll upload a cap where it "works".
Here it is. Sorry for using rapidshare.
To get it to display properly, I changed the 10% layer scrolling speed to a 50% layer zoom, made the layout its-self bigger, and moved the the contents of it towards the centre of the layout.
