Ads blocking the board

Hi, Just starting having this issue 5 minutes ago.

After I finished a game an ad from a local power company turned up covering part of the board (around E3 and G3). But I can't get rid of it, if I hover my mouse over it it starts to expand and clicking on the X shrinks it to the original size. 

The main issue is that if i try to start a new game the ad stays there blocking the board. I've tried ctrl F5ing, new tabs. Any other ideas?

Thanks! We are looking into this. I think a new ad network (VDX BY EXPONENTIAL) is causing this. I'll get it shut down!

That was quick , its now fixed the ad appears in the top left corner away from the board.

Ad is blocking part of the board again.
