I don't really post in forums but after contacting FMscout earlier this year concerning this the same issues are occuring. It's a real shame as I love the site and it has so many useful resources and articles but the ads down the sides make many pages unreadable.

Hi Jon, thanks for your feedback.
From your screenshot I see 2 ads with the one on the side causing trouble by going over actual content.
That shouldn't be happening, meaning that the boundaries of actual content should never have anything crossing over to affect.
What it should happen is show that ad if there's enough free space outside the content, or don't show it at all.
It has to be a bug in the script the ad agency is using. Not sure if it's related to specific browser though.
May I ask: Are you using more than 100% zoom in your browser?
Either way, I'm raising the issue to them to fix it asap (assuming they'll be able to investigate tomorrow).
