Fivestar appears on content type, but can't vote I have problem with Fivestars module, (Drupal7).

It is configured in field and appears on content type page, but cannot vote
(like voting is disabled - when inspecting with firebug, i see no Javascript activity over stars, and no any possible javascript conflict.)

Permissions are set correctly.

What in the world could cause this ? 
(it seems more-less like plug-and-play module :D )
When adding the FiveStar field,


If you choose "Rated while viewing" , that means all users can rate the node (with permissions) can rate the node. This is ideal to allow users to rate how well the article was writtem etc). 
If you choose "rated while editing", it will make the rating field disabled (static field) for other users than the node author. This is ideal for review nodes to allow the reviewer to leave their ratings while making the node or any other entity.
