I had made some changes earlier this summer to handle resizing (manually). Obviously this crash gets triggered by Moom which doesn't follow the manual resize use pattern.<br>>>> <br>>>> On Sun, Jul 3, 2016 at 5:36 AM, Bernhard Pieber <bernhard@pieber.com> wrote:<br>>>> <br>>>> Dear VM developers,<br>>>> <br>>>> I can reliably crash the latest stable CogSpur.r3732.app using the Squeak5.1-15113.image when I resize it with Moom (http://manytricks.com/moom/) right after starting the image.
