One of the headaches of using a website is spending time writing a long piece of text, then accidentally clicking a link or the "back" button, and losing all that work.
I've added a new feature that tries to prevent this. If you start editing a page or a comment, and then click a link or button before saving, an alert message will pop up, and give you the chance to stay on the page so that you don't lose your work.
It's working ok for me using the Chrome browser on Windows. If you use a different environment, please could you try it and let me know if it works, as well as telling me your browser and operating system. Also please let me know if you find this new feature stops anything else on the site from working properly.
