Whenever I get attachments I usually just drag them onto the desktop from the Mail window. Today though, I noticed that when I do, it sets the permissions to Read-Only. I'm listed as the owner, but I have to manually change the permissions to give me Read/Write permissions so that I can edit the file.
However, when I click the "Save All" button in the message, and save the attachments that way, it automatically gives me Read/Write permissions.
Any one else experience this?
