title: Emacs hang after installing gtk3 in windows 7
body: <p>I recently decided to use emacs as I am starting to learn common lisp. But here is a problem that I feel that I must have done something wrong. After googling around for the past several hours,  I still couldn't figure out why. </p>
  
  <p>I am using windows 7. Installing the most recent emacs (24.5) with quicklisp, slime, sbcl etc are all fine. Then I started to install gtk+3 according to <a href="http://www.gtk.org/download/win32_tutorial.php" rel="nofollow">http://www.gtk.org/download/win32_tutorial.php</a>. And it went well: I can run gtk3-demo. The problem is that after I put the path in the system environment, emacs was not responsive anymore: When I run runemacs.exe, it starts a window, then hang with a blank window (the menu appears). It can start fine after I remove the /dir-to-gtk-bin/ from the path. </p>
  
  <p>I believe that there must be something wrong with my system setup, since emacs should work smoothly with gtk+ devleopment. Could you please give me a hint on where to start checking? Thanks very much for your help. </p>
