Hello, What is the extension of the current file edited in oXygen when you run the action Open in Browser? Do you have a browser path set in Options -> Preferences -> Global -> Default Internet browser? What is the application associated on your system with the extension of the edited file? Do you run oXygen on Windows or other platform? Regards, Sorin Boojum wrote:
