By the way, I update the four dylibs of my 7.1 version by the ones coming from 7.2 : libgluegen_rt / libjogl_desktop / libnativewindow_awt / libnativewindow_macosx

Doing this, when I double click the app, the app icon appears in the task bar but no window is showing. So I also update gluegen-rt.jar / jogl-all.jar

Nothing changes, the app does not show.

If you know what to do, I would love a hint

If you have to search for an answer, forget it. It currently works fine, I will not do this update.
