Opened and made a copy (Save As) of an existing doc in ID 17.4, moved to ID 18 when it became available. Replaced about 2/3 of the existing material with new text or images. Found one specific text box that crashed when I tried to delete it. Tried deleting the text in the box, another crash. Tried deleting text in chunks, and got down to just one letter that was causing the crash.

Fix not required. This is a result of regularly importing Word docs from other people. (The proof is the document recovery notice: the recovery called for links to 1400+ items, when I know that the doc should only have 60 at most.) Also a result of duplicating a doc instead of using a template.
