A while back we upgraded from Audition 1.5 to Audition 3.0, but apparently when you open a session file by double clicking it in its folder, it opens Audition 1.5. These are files created and saved using 3.0, and they open normally in 3.0 if you launch audition first and then use open session under file. I tried right clicking on the session file to change the default program that Windows 7 uses to open it, but it only lists Audition. It doesn't give a choice in versions, though it does us the icon/logo from 1.5.
How can I change the default to Audition 3.0?
