First, I got messages from startup that Operator will not work. This happened the first time I ran L6b15, but this time I've got pics.


Operator works fine, but the messages were conflicting - maybe it has something to do with the library.
The other, more puzzling issue is that any project/file/song I open that was created or saved in Live 4.1.4, 5.2.2 & 6 Betas 15-21, indicates that the paning is off-center like tracks 1 and 4:

but the arrangement view does not quite agree.

This happens to the master pan as well. I think this may also affect the native plugins like Impulse.
I trashed the .cfg file and started anew and also made a new template and saved it. All L6.0.1 songs are fine, but when I open anything from the previous versions, the pans are not center. Maybe it was the suggestion of off-centeredness, but I felt like the auddio panning was off-center as well - I can't confirm this because I don't remember exactly how I set things (although I usually pan for a balanced sound).
Oh, I should also say that I used 4.1.4 and purchased 5.2.2 only as a means to upgrade to 6. I have used L5 for only a week before digging into the beta releases and finally upgrading to 6.
Hope you can help with this.
Thanks,
