WP-Polls problem - can't vote

http://www.lactivist.net/?cat=596

WP Polls seems to be stuck on showing the results and you can't vote. I have checked the permissions and they are ok, I have checked that <?php wp_footer(); ?> is in the footer file and I have de-activated as many other plugins as possible.
Ohh, and I re-installed it to an earlier level as that used to work with the default theme.

Last night I got a loop when I asked to see the results of a poll, it said something like it was still working on my last action, when I closed the box the same message just came up again.

Any help much appreciated.
