Stream hanging

Ok so I love the new G+ interface. Now that that is out of the way I am getting frustrated by the way the stream tends to stop if I go to another app or window then return to my G+ window and the stream is stuck at some previous point in time.

I like leaving my stream running and returning to it from time to time then scrolling through all the stuff I missed. I'm assuming this happens for I wrong?

EDIT: oh and what is this at the bottom? Shared from stream stopping which is the search I was viewing when I made the post...what if I had been searching for something I don't want people to see? YIKES
