title: NSSplitViewController based application almost never launches with the correct size
body: <p>I have this app that uses a <code>NSSplitViewController</code> as the root and has a  <code>NSTabViewController</code> connected as its detailViewController.</p>
  
  <p>This app is set to launch at 1024x768. The left pane should launch at 320x768 and the right pane (where the tabViewController is), should launch at 704x768.</p>
  
  <p>From 10 times I run this app, 9 times it will launch with the incorrect size (about 500x500). Other strange thing is that this app should not be scalable, but if you hover the mouse near the window border you see cursor indication to scale.</p>
  
  <p>I want this to launch at the correct size and have no scalable option.</p>
  
  <p>Both of these settings are on interface builder but are being ignored.</p>

  <p>How do I solve this?</p>
