As requested in the installation note, I've wrote at the command prompt: chmod +x yEd-3.9.2_setup.sh (or sh yEd-3.9.2_setup.sh) and was able to install and run yEd under Linux (Debian) with root previleges...Unfortunately, I don't want to run it this program as root user. What is the recommendation and procedure to run as a normal user. Is the command: 'sudo yEd &' the only solution? Let me know. Thanks.
