3D PDF Publish makes Inventor visible

A partner reported that when using Inventor invisibly in the background to create 3D PDF, then the Publish command of the 3D PDF Add-In causes Inventor to become visible :-/

He was kind enough to also check with Anark (the creator of the 3D PDF Add-In) about it :) and they said the issue was solved in Inventor 2017 SP1/R2 and is of course also available in 2017.3 Update.

I checked things with Inventor 2017 SP1/R2 and indeed the issue seems to have been solved :)
