I'm not sure how I created this same problem, probably pasting without having a box selected. Wasted an evening's work, but never mind it is a beta after all. However, without doing some real work with it I'm not going to test it in the way I will use it. I had been saving my file regularly during the evening. When I restarted publisher after the crash it informed me that I had a recovery file, would I like to load this. I said yes and it promptly reloaded the empty file that I had started with at the start of the evening! I exited without saving anything and tried loading my file that I had been working on. The timestamp said that it had last been edited at around the same time as the crash, but it was the empty file that I had started with. That was more frustrating than the initial crash. This may be another bug.
