I'm new on this place ! So, welcome to me
I have an issue with Natron, when I launch the application, my Safari can't load any page. When I close it, that works fine.
Don't know why, but Natron is the problem.
Natron has internally a webserver to handle documentation and listens to a local port which can set in the "Preferences/Documentation/Documentation local port." It probably is interfering with Safari in some way, you could try to change it, or set documentation source to "None"
Why a webserver why not QtHelp? Or html pages without a webserver?Thanks
