I can load my puzzle, and just move it around (usually looking for the ends of a strand), and the client will crash. See attached crashlog.txt. I'll try to update with the usual files from inside the app, but wanted to post this first.
OK, here's the log.txt. The debug.txt was zero length.
I uploaded for scientists the pose that is crashing. I'm trying to close all the cuts, but it crashes before I'm successful. I tried creating a new track from the initial pose, but it crashes also when I trimmed the leftmost strand and just tried doing a shake with nothing selected. Next step is to see if it happens on the downloaded initial pose. One thing that might affect it is that I had wiggle power on High when I got the crashes. Will try again with Auto, as when I started. «No joy. Still crashes.»
