DMG mounts but does not auto-open I have a DMG which I downloaded using Safari. When I double click it, the volume mounts but it doesn't open in a new Finder window.

Any idea why this would happen, and how I can fix the DMG so that it does? (PS - I've created the dmg and hope to distribute it, but it not auto-opening sucks)
Here are a few online guides to creating auto-opening DMG files.

From the first guide by Bill Bateman, step 23 seems to be the key:


  Click Convert on the toolbar. Enter a new filename and make sure the
  image format is compressed.  Click Save.  This creates a new image.


Another guide (via this post) has a bunch of information. The info regarding the auto-open piece is here:


  But we found that the .dmg doesn't always open up its window when
  mounted. This “autoOpen” utility solves that problem:

One of these two guides should help you set up the auto-opening DMG.
