StoryGrinder has been updated to version 0.8.7 with the following changes:

• Web archives for scraps in the Scrap Box must be are managed separately from temporary scraps associated with stories. This means that the cache referenced from Preferences refers only to data associated with stories, and clearing the cache will no longer remove cached Scrap Box items.
• Spurious reloading of scraps in scrap box upon selection should no longer occur.
• The sort order of the Scrap Box list is now saved between sessions.
