title: tmux and multiple PuTTY/KiTTY sessions
body: <p>I recently swapped from <code>screen</code> to <code>tmux</code>.</p>
  
  <p>I have two physical screens, and I used to open two PuTTY sessions to a unique SSH server.
  This two sessions are attached to the same <code>tmux</code> instance.</p>
  
  <p>The problem is when I change the current window on the first PuTTY, the second PuTTY is also changed.</p>
  
  <p>Do you know how to have two different visualizations for a single <code>tmux</code> instance?</p>
