Documents saved can not be reopened

Using Curve 5.1.1 on Sonoma 14.0 release version.

  1. Make a new Document.
  2. Save that Document (locally on disk) and close it.
  3. Open document … that fails in two ways.
    a) Double-clicking document in Finder tries to open TextEdit.
    b) Choosing File > Open Recent - get the error message “An Unknown Error occurred”

Any ideas what’s going on here? No special characters in the name or anything odd like that.

OK. Worked it out. Curve is not adding .curve to filenames when you save.
