Rating stars appear after 5 seconds delay

Hi there,

I have installed the Comments plus plugin (in my developing site), but the following problem occurs: When i select the Wordpress Tab, the stars for the rating do not appear immediately; instead, they appear after a 5 seconds delay. (See the attached image)

Except from this problem, i would like to ask if it is possible for the facebook, twitter or google users to be able to rate, except from leaving only their comment.

Thank you in advance,
Dimis
