Using arelle 1.2020.05.10 (64-bit) git master branch, with Python 3.6.9. Installed Edgar Renderer 36.0.2 git master branch. Opening a iXBRL file either from local machine or through URL does not open an internet browser to show the iXBRL document. I am able of starting the "Arelle web services" and connecting to localhost:8080. But I would prefer to have the browser triggered from Arelle GUI.
No visible errors in terminal. In Arelle message I see:
[Warn] "The rendering engine was unable to produce output due to an internal error. This is not concidered an error in the filing.
