When I click on the Finder icon in the dock, it always used to open a new window for me unless I already had a window open. In that case it would bring that window to the front which was no problem. But now if I have no windows open, and I click on the Finder icon, no new window opens. I have to hit Command-N if I want a new window.
Which setting do I have to change, so that Finder will open a new window if there is not already a window open?
