Under OSX I renamed my Oxygen 11.2 install from "oxygen" to "oxygen_11.2" then unpackaged the tar.gz for Oxygen 12 and moved the resulting "oxygen" dir to my Applications directory. I was then able to start Oxygen fine and verify that v12 started. However, from Eclipse, when I try to open a file in Oxygen by navigating to the Oxygen.app icon in the "Choose external application" dialog, the icon shows as a text file, not an application, after I choose it, and trying to run it gives a failure with this detail message: Error opening external editor (/Applications/oxygen/Oxygen.app). Cannot run program "/Applications/oxygen/Oxygen.app": error=13, Permission denied Any idea what the cause might be? I don't remember having this problem in the past.
