title: What determines the monitor my app runs on?
body: <p>I am using Windows, and I have two monitors.</p>
  
  <p>Some applications will <em>always</em> start on my primary monitor, no matter where they were when I closed them.</p>
  
  <p>Others will always start on the <em>secondary</em> monitor, no matter where they were when I closed them.</p>
  
  <p>Is there a registry setting buried somewhere, which I can manipulate to control which monitor applications launch into by default?</p>
  
  <p>@rp: I have Ultramon, and I agree that it is indispensable, to the point that Microsoft should buy it and incorporate it into their OS.  But as you said, it doesn't let you control the default monitor a program launches into.</p>
