If the newblur tab in Chrome loses focus for another window and then returns the article disappears.
When the tab with newsblur gets focus again and the mouse is used (scroll wheel) the article gets marked as read and then the page refreshes. If the view is set to show unread only this means the article cannot be read until the feed is refreshed and the article is opened from the read status.
I read all articles showing unread only. So when the page refreshes I have to show the unread to get back to the article. It's a real pain.
