update #1:
I changed the box.com settings to those specified on:
Sony instructions
Server:
https://dav.box.com/dav
Port: 443
Username: my username
Password: my password
Sync Folder: /
Destination Folder:
I read the new instruction manual provided with the software update today.
Now when I have a document loaded, I can select the menu button and then the Send option. That does send the document to my Box.com account!
But ... I still have not figured out how to download a document from Box.com. That was my main reason for this exercise
. Uploading a modified document is nice though.
