title: P4Merge forgets my comparison method preference. How do I set a default value?
body: <p>When running P4Merge, the comparison method is always initially set to 'Recognize line ending and white space differences' (aka all changes). I want to use 'Ignore line ending and white space length differences', but I have to manually re-set this every time the tool runs.</p>
  
  <p>I have changed the setting:</p>
  
  <ul>
  <li>with the toolbar button</li>
  <li>in the preferences dialog</li>
  <li>on the File menu</li>
  </ul>
  
  <p>and it never sticks. In fact, the preferences dialog entry is reset every time I go back to the menu, without even closing the program. I have changed the setting before using the Exit command from the File menu and before closing the window, and also before saving a merge.</p>
  
  <p>In the past I was able to save my setting and have it be remembered, unfortunately I don't have any recollection of the software version involved. I was using P4Merge as standalone and none of the rest of the Perforce suite was installed.</p>
  
  <p>I can update with any other supporting information that might prove relevant.</p>
  
  <p>[Edit: It's the radio button setting in the preferences dialog that ignores changes and resets every time it's viewed, not the File submenu.]</p>
