Greetings,
Interesting issue here: one of my document makes Publisher crash immediately when I try to move/delete a text frame. And it seems to me it is related to pinned images in my text. It started after I had almost all of my images pinned, it stopped after I removed all pinned images and groups (I have some groups with a few images and a text frame). Well technically, I made a new document with the text and left the images away, as deleting a pinned image from the old file also crashes Publisher. I tried unpinning and deleting afterwards, that seemed to work for certain images, but not for all.
Publisher versions affected: 1.7.3 (macOS and Windows, I normally work on macOS Mojave but tried editing my document under Windows 10) and the current beta 1.8.0 (macOS)
Can I send you the file for further issue tracking? Try to delete the first frame on page 2: guaranteed crash :-)
best wishes, Serge
