Hello Dick, You are right, I haven't given all needed details for reproducing the error. I was a pain (because now has some moments when it's working) but here are the steps :
1. open the board and do not change the zoom (i have a clue that on different zoom magnifications it is working) 2. move the mouse at coordinates x3.2 and y0.8. 3. right click and in selection clarification choose zone. 4. delete zone and the pcbnew it crashes. I'll find a way to send you the board file. Warm greetings and peaceful Christmas, Daniel
