I did maybe 20 jigsaws and was saving them all. Then I would start another and put it into saved puzzles. When I came back to it I found it had undone a lot of the jigsaw. This continued to worsen with completed puzzles disappearing as well. I contacted tech support and was told to try a different browser. No change. I kept trying jigsaws and tech support. They didn't do much at all to help with suggestions that made me think they did not know a whole lot about saving games and problem solving. Thought I would give it one last try and finished the edges and saved it. Then when in to check it and it wasn't even there. The one I had finished earlier was now only half completed. No point in keeping on with no assistance from support. Give it a miss there are plenty of others out there.
