Thank you, that would be very helpful. When it happens after doing over three quarters of a complex image, it can be very frustrating indeed.

pdncrash.64.log

I've tried, and I'm not being allowed to do it. This has just happened again a few minutes ago, I got a page of crash logs at first, but when i tried to work from it, they just disappeared.

I am increasingly getting this message, usually after I have spent quite a long time working on an image. It always occurs when I am hitting edit and undo, and always on the third key press. It seems to be happening more after every update, but not consistently, as I still sometimes complete long and complex tasks without it happening. Any ideas please? It is irritating and very frustrating.
