An autosave feature has been implemented for VHV. When you leave the VHV website, either accidentally or on purpose, the contents of the text editor will be saved. If you return to the editor within an hour, the previous contents of the editor will be restored automatically. If you do not want the old contents loaded, add the k=e parameter to the URL, such as http://verovio.humdrum.org?k=e, which will erase the autosaved contents.
