I recently upgraded to Snow Leopard, and therefore have Quicktime X in addition to Quicktime 7 Pro (I paid the $30 to upgrade). Since I have the Pro version of Quicktime 7, I want all movie files to open with Quicktime 7. I opened the Get Info window for a .mov file I just downloaded, switched the default application to Quicktime 7, and pressed the "Change All" button. However, if I close the Get Info window and open it back up, the default application has switched back to Quicktime Player Launcher. How do I get Quicktime 7 to be the default application for all Quicktime files?
