I've left an image in lascaux sketch, though I don't want to draw one image to simply start working on another. Can I recover it another way?

I haven't a clue what you're talking about.

Jesus Christ Manifesto, I thought so. When one's browser fails in the middle of the picture, 2Draw saves it. But the picture I was working on as my browser closed was a big picture. In order to normally retrieve this picture, one has to draw a different picture for the 2Draw board to give up and submit the picture you started earlier when the browser closed. Is there another way to retrieve it?

I'm not sure if this problem is lascaux's fault, or 2draw's fault, cause I still don't understand. >)

gurgle. That's all right.
