Hover over stars, highlights rating but if submit zero rating

Hi

Hoping you can help resolve an issue for me. I’m using Multi rating Pro and have noticed an error.

When you hover over the stars they automatically look like they have been selected. However if a user clicks submit then a zero rating is given, because the stars have not actually been selected.

Is there a way to either fix it so that the stars do not get highlighted when they are hovered over or that when they are hovered over it is equivalent to clicking on them?

If you want to have a look at my website to see the problem its http://wiki-dev.org

Otherwise a great product, thanks!
