Bump -
So I do the whole 'Get Info' > 'Open With' thing, to try to get a particular file type (.seq) to open with TextEdit by default. When I click "Change All...," I get the "are you sure?" dialog, to which I click Yes - however, the Get Info window immediately reverts back to the old default application (QuickTime), and all files with the .seq extension still call up QuickTime as the default app. Anyone have any idea why this preference for TextEdit isn't sticking?
