I copy a collection of simple text boxes, circles and a few arrows (I've drawn an organogram) from my page.
I go to my master page.
I paste. Publisher crashes immediately.
I did this a few times in a row to confirm that it happens consistently.
If I manually select the items, it works just fine. It only crashes if I have selected the items by using the command "Select all", then copy and paste. Clearly, I'm picking up something extra that's not a physical object on the page. That invisible something is causing the crash.
