I'm getting that most of the time in IE11. No problems with Chrome.
Page loads up to the bottom of the vertical advert on the right hand side of the screen and then the scroll bar vanishes. Can take a few attempts at refreshing for it to work.
On other things:
Had the IHG box popup once in Chrome.
The square moving advert at the bottom of the screen seems to affect IE now and again. Causes things to start jerking, randomly pauses things like when typing and letters won't appear etc.
