oh and double tap/click in the project window also doesnt work..
What, exact, version number of AE CC 2014 is this you're using?
What exact OSX version number are you using?
Have you tried deleting preferences or any other troubleshooting steps? If so, what?
tbh i havent tried deleting the pref file.
I used to be good at trouble shooting, but nothing seems to be the same as it was. I find it har dto locate pref files now. plists dont show software pref files anymore??
Resetting preferences with command option shift on start up makes no difference
