Saving taking extremely long time

Suddenly when shutting down and Studio One ask if I want to save and I say yes it hangs. It's now been over half and hour and it's trying to save. It's stuck here. I found an old post on line from 2013 with the same problem.

Packaging: Editor.xml I will have to force a shut down as it's still going on.

So far I like the program very much. It's much easier for me than Sonar was but this makes it in usable. It started after I tried the quantize feature. Not sure it that's relevant or not.

Thanks, Michael
