title: Visual mode in vim not working
body: <p>This might sound like a trivial issue but it is bugging me for some time now. I have been using Vim on a Linux server since long and I used to access this Linux server using PuTTY in a Windows XP desktop computer. </p>
  
  <p>Now I have moved to Windows 7 and still use PuTTY to access the same server. The problem is that visual mode has stopped working on the server. When I was on Windows XP, to enter C style comments <code>//</code>, I would do:</p>
  
  <ol>
  <li><kbd>Ctrl</kbd>-<kbd>V</kbd> to enter visual mode</li>
  <li><kbd>Shift</kbd>-<kbd>Down arrow</kbd> to select columns across lines</li>
  <li><kbd>Shift</kbd>-<kbd>I</kbd> to enter insert mode and add <code>//</code></li>
  <li><kbd>Esc</kbd> to copy text to columns in all lines</li>
  </ol>
  
  <p>Now in Windows 7, the behavior of PuTTY/Vim has changed. When I now press <kbd>Ctrl</kbd>-<kbd>V</kbd>, it enters visual mode (I see it in the status bar). But when I press <kbd>Shift</kbd>-<kbd>Down</kbd> to select columns across lines, Vim exits visual mode and goes to command mode. </p>
  
  <p>I am not able to figure out if it is an issue with Vim or PuTTY or Windows. Since I have not modified any Vim settings on the server, I suspect it is some configuration with PuTTY but I am not able to figure out what. PuTTY version is 0.63.10044.0, Vim is 7.0.</p>
