Quote from the AS dictionary:
So my question is, why does this script fail (I have a movie open in QT already):
tell application "QuickTime Player" to set show detailed movie info window of movie 1 to true
I’ve tried getting QT to activate first, quitting and restarting, and different movies. Each time it compiles fine, but comes up with a “NSUnknownKeyScriptError”.
Simply telling QT to “get show detailed movie info window of movie 1” returns false, so I know the property exists.
