the problem seems to be that since the poll is an iframe, when the vote/view buttons are clicked, it opens up the polls dedicated page inside that iframe as well. basically, the iframe is being treated like its own separate, mini browser tab inside your site

the only ways i can think of to fix this problem is to either put the polls code directly into the index pages code, or to maybe try and put the target="_blank" attribute inside the tags for the buttons in the poll. its an attribute that should result in the pollcode page opening in a new tab, though i havent tried it myself yet. hope this helps ^^
