I was looking at the poll in this thread and took a look at who voted for the first option. There were 55 voters at that time, so the list was really long (see attached screenshot). The popup needs to be tweaked to allow for lots of voters (perhaps some sort of AJAX pagination). Scrolling the page down doesn't help since the popup doesn't move.
I've made it scrollable, which should help unless there are a massive amount of voters. Still, could do with shrinking the list or handling it a bit differently. The poll stuff doesn't look great currently.
