its a virus/malware on your computer. i have had that problem before. it will only show on certain sites. i actually had a big ad banner appear on this forum but it only did so on one browser so i knew it was malware on my computer. i.e. when i opened it up on windows explorer it showed a big 1/4 of the top of the page ad banner and on mozilla firefox it did not. even though i got the malware removed i am still in the habit of using firefox for the forum, yahoo ,netflix etc. for whatever resaon i find on my computer that ebay works better on windows explorer as do certain other sites. weird stuff.
