Norton Internet Security 2013 and Chrome not working well any more.

For some reason, NIS 2103 and Chrome for me don't work well together all the time any more.  Sometimse my password vault doesn't come on, sometimes it does.  Also, the NIS search advisor (or Norton Safe web) doesn't come on in any search engine, most of the time. And the Norton toolbars won't come up at all. In the Chrome Extentions, I see that Norton is enabled, but clearly is not working really well. Really like Chrome, so if anyone has info as what happened a few weeks ago and how to fix it, that would be great, thanks.
