On OS X El Capitan hoover issue
On OS X El Capitan when hoover over news instead opening anoder preview dialog it colapse main dialog so you cannot see news only you can click on it and if you want another you need to click again.
This was also happening before El Capitan. If I'm not mistaken, since Mountain Lion. Just to point out it might not be an Mac OS version issue.
Yep, happening here too. You have to be fast and fairly deliberate with your click to get it to actually select and open the item you want. The slightest delay will cause the drop down menu to disappear.

Well this is a dealbreaker
