NIS 18.5, Safe Web checkmarks in Google search

I am having problems with Norton Safe Web checkmarks which should be seen in Google search results, BTW using IE8. If I type in Google search no Safe web rating marks are displayed alongside results. I have to refresh (F5) to get them seen what is quite obtrusive. Other search webs (like Yahoo) show Safe web rating correctly and instantly. Problems just at Google. I am sure that it worked with Google as well till recently but I don't know what happened now (Windows, Google or NIS updates?). Did somebody else encounter such strange things with Safe web and Google? A help is welcomed.

Thx.
