Hi Finema,
the CustromUI runs so far and reacts as desired.
Unfortunately, however, no thumbnails are shown in the Obj Library.
Clicking on the saved. 3DM files does not load the models and new models cannot be saved.
The Ext Scripts window will open as expected - but some scripts won't run at all or abort with an error message.
The Snapshot function works like it should.
