hi Debbie,

it happens on any store going from the MarketPlace home page or from an external link if i'm using Firefox; if i use IE (after allowing pop-ups) it opens a new tab for the store, does a little side-to-side jiggle, and the Facebook Like button is down toward the bottom.  if i use Firefox from the home page the store opens in the same tab but after about 3 seconds it opens a blank page with the Like button in the top left corner.

i'm sure it's something in by settings otherwise i would see a lot more threads about it. ;)
