The Pro Sites page renders differently in IE9 as compared to Chrome & Firefox.
The first image is Chrome - Firefox renders the same.
The second image is IE9 as it appears when the page very first loads. You'll notice that there is a section (top left) which shows up as being selected - but I didn't select it. The PayPal button also shifts right.
The third image is IE9, after selecting any other option besides the first one. Notice the odd color change that occurs?
There seems to be a browser issue happening so I thought you might want to look into it.
