"Couldn't Save Your Note"

I’m trying to save a note via my sorter. I enter the note, hit “Save,” and get the above message: “Couldn’t Save your Note. It has been saved on your Desktop an Sorter Note 1.txt” Odd behavior-all has been well up to today. Ideas? Thank you.

Maybe there’s a permissions problem on ~/Library/Application Support/DEVONthink Pro 2?

If you reboot, does the problem persist?

Perfect! Thanks. (if only they were all that easy, eh? LOL)
