I am new to Mac and use Mountain Lion. I am bothered by what I hope is a preference, not set properly. When I double-click a screen shot on my desktop, Preview opens but it also opens for all other files I recently opened with Preview.
TextEdit and even Excel do the same thing.
I open the file I want to see, not the one I already looked at.
I notice that when I explicitly close the files, they will not open automatically. I want this to stop.
How do I do this?
