This forum is for seeking solutions to technical problems involving Digital Performer and/or plug-ins on MacOS, as well as feature requests, criticisms, comparison to other DAWs.
However, under the Digital Performer menu item, I do have a Quit option. When I clicked it, I got the "...unsaved changes..." dialog and saved that way.
Curious...

(The sequence was not in play, BTW, or were there any other processes going on that I was aware of.)
Early 2009 Mac Pro 4,1>5,1 3.33 GHz Hex Core Intel Xeon OS X 10.8.5 SSD (32 gigs RAM) DP 9.51 PCI-424e / original 2408, 2408mkII, 24I/O, MTP-AV
If you restart DP does it fix it? Sounds like the app is loosing track of the OS directory. I might have seen this once or twice over the years. Maybe just once, but it sounds familiar.
The usual Disk Utility suggestions apply : Repair permissions. Repair disk(s).
As I was posting this, I left DP running to make sure the anomaly didn't correct itself over time, and then I wanted to check the Quit option that I mentioned.
Then I shutdown, let the Mac sit for about a minute and restarted.
The very first thing I did was repair permissions. Took about 20 minutes. The three main "culprits" were Java, Core Services and Frameworks. About 15 or so repairs for each.
Then I ran MacJanitor and Preferential Treatment. Got one error with PT.
Shutdown and rebooted and continued working for the rest of the afternoon.
I have not gone back to this particular edit file, but everything seems AOK right now.
Thanks...
