i have been testing polls on my site and here are the current problems.

If you create a poll with 2 answers "yes" and "no". if someone votes on "yes" the poll will go to 1%?!...if someone votes on "yes" again it will go to 2%. if someone then votes on "no" it will go to "yes" is 67% and "no" is 34% . that adds up to 101%??!

It's possible to vote twice on polls by not being logged in and voting and then logging in and voting.

Once the user has voted the display of the Poll should always display the results by default instead of the option to vote. (unless the admin has allowed the user to vote multiple times)
