IIs it a problem with adblock maybe ?
If it is then wouldnt you be able to prove that by removing / disabling ad-bloc and loading the page?
Also, if it existed in TMX, then it may not be a MX bug, as MX is a new project. How many other pages/sites do you have problems with? ^^
it be worth you clearing all your temporary interent files (cache) and force reload the page, if it can somehow be possible that your download of the banner got interrupted but your browser doesnt think so.
