Hi Yordan, To test your zoom patch, I opened my old json file that I sent you, but noticed that it comes up without the right dimensions for the graph. Here's a screenshot: http://rostedt.homelinux.com/private/ks-off.png If I resize the window it will eventually go back to normal. But I figured I'd let you take a look. I'm guessing it has something to do with the saved json file was for a smaller window than the one that opened it. -- Steve
