G4 and Glyphs Viewer

Glyphs Viewer does not show nothing but a white screen with G4 {4.0.1 (4004)}. Latest Viewer version from the Appstore… “Enable Ext. Viewer” in Settings is enabled and from what i can tell the Viewer is recognised by G4.

Works like a charm with G3. Anyone else having this problem?

That is a known problem. It is on my list. Thanks for the reminder.
