SOMA won't save

[Mudbill]

I doubt the sharing part has anything to do with it. I would suggest you undo that part if you don't want any other user on your network to access the files stored in that folder, because as it is currently, someone on your Wi-Fi network has the ability to read and save files to your folder, which is rarely desireable.

It's possible the security settings helped, though odd if moving the folder was what caused it to apply.

Did you move the Documents location via the "Location" tab on the folder properties?
