Scapple crash on export to OPML

Hello, every time I try to export my Scapple file to OPML format, it crashes and the OPML file is never created. Reproducible steps:

  1. Open Scapple file
  2. I choose File --> Export --> Outline Markup
  3. Leave “Selected Notes Only” unchecked, can either check or leave unchecked "Create “notes” field
  4. Click OK
  5. File dialog opens, create name, click Save

Scapple will crash. Every time. OPML file is not created, and there is no Scapple error message given.

Thanks for any help you can offer.

I’m still unable to export to OPML. I really need to get this out of Scapple and into Scrivener. I’d appreciate the help.
