Thanks for your reply. I use the most recent downloaded release (version 188.8.131.52), and when I click the ‘Install -> Apply Hotfix’ menu, I get the following error messages: 1) hotfix dataset could not be installed; 2) Hotfix does not exist or failed to apply hotfix! Please wait for the next release. I don’t use the git version, but I’ll give it a try. But please let me know when you fix it so that I may update/download the updated version.
