My It helpdesk updated my IE browser yesterday (I was having issues getting onto the PureGym website and they thought it might help- it doesn't.)

anyway. DiS now looks all different for me- better in some ways (I CAN SEE THE EMOTICONS NOW!!!) but TERRIBLE in the fact that the ads are always at the top and can't be hidden by scrolling, and sometimes A VIDEO PLAYS IN THE BACKGROUND. This can't be allowed. Is there a way I can go back or get a plain text screen as this is killing my buzz, giving me a migraine, and probably going to get me sacked as it's so obvious I'm not on Companies house website now.
