Poll-form generates value for action-attribute automaticaly

Hello,

I am currently the administrator of the Drupalsite http://www.proffsbutik.se where as when you vote on a poll on the frontpage you are automaticaly taken to another (seems to be random) node on the site. The vote itself do get registered, it just moves the user to a new page where the user should remain on the startpage after voting.

If I look through the source in a browser, or inspecting it with firebug, the form-tag has automaticly added a value to its attribute action which is a random node on my page - and seems to change from time to time to a diffrent node as I post/edit content on the site.

<form action="/imce?app=tinymce%7curl@src"  accept-charset="UTF-8" method="post" id="poll-view-voting">

or

<form action="/produkter"  accept-charset="UTF-8" method="post" id="poll-view-voting">

but it should say:

<form action="/"  accept-charset="UTF-8" method="post" id="poll-view-voting">

Though, when logged in as administrator this problem do not occur and the poll works perfectly.

Does anyone have an idea why this is happening and what I can do about it? I havn't been able to find a similar problem in the forum or searching the web, but I hope it's not to difficult to solve. ^^

Thankfully,

Sebastian.
