I'm using many "spaces" to separate different tasks, and I have blocked the "spaces" switching through this configuration of Mission Control:
Nonetheless I have a remaining problem with "Spaces" I would like to fix. I have the same usage problem under "Mountain Lion" and "Mavericks".
Let's say I am on a "space" with a lot of work in progress. I want to stay focused on this "space". If I want to switch to another application I just have to click on its icon within the Dock. This application become active without any unwanted switch to another "space".
But this function is failing for the Finder.
If I want to switch to the "Finder" and click on its icon within the Dock, then I'll be switched to a specific "space" where the Finder has an opened Window.
The Finder option related to this function is set as follows:.
I tried this setting on the basis of this very similar old question: How can I open a Finder window in Desktop without switching to another one?
I would like to understand on which mechanism this particular "space" associated with the Finder is choosen.
I would like to get rid of this unwanted and ununderstood switching mechanism.
