can someone explain why my 'Quicktime preferences' under OS X.4.9 do not launch anymore? Any time I want to open the application, it does not launch.

quicktime

Could be any number of things. Try trashing your com.apple.* preference files and any *quicktime*.plist ones.

Because something broke. Reinstall from a package installer... and make sure you did not put anything in important places, like /System/Libaray/Quicktime and /Library/Quicktime, like old, duplicate codecs, and what not.

I trashed all com.apple prefs and quicktime.plist but it still does not open.
