Visiting homedepot I see the popup, clicked the "What's this"?" link and the dropdown displays some text that cut-oof at the bottom. It appears that WOT is not reading my screen resolution very well and I refuse to get a different monitor to see it all. :)

I contacted the user via PM to get info about screen resolution and a screenshot.
