Syngenta. That is the company placing the ad since this first started over two months ago. Different ads also, same company. It stopped for a few weeks.It looks like the AD is making it center to it, (in both instances the ad is in the center of the screen), thus messing up the rest of the layout.
I've told the higher up about it and they are looking into it.
SRG click on the ad and tell me who the ad is for please.
