Question

For example: open this simple jsfiddle and place your windows like this: :
Then place cursor over the jsfiddle red region to make it :hover (green) and now move cursor to the other window. Region still green! How to avoid of it?

Answer 1

You have to click on the new window in order for the hover element to lose focus. The jsFiddle window still has focus, even when you hover over a different window. Window focus won’t change until you click on the new window.
