Hi Mattias,
We managed to reproduce and fix the elements bug that you mentioned. We pushed out an auto update, so to get the latest version please close 3ds Max and reopen it. After starting the Scene Manager please go to Menu > About and you should see the following version and date:
Regarding the batch render Cancel button, you are right it doesn’t cancel the process. Unfortunetly it is not possible to stop it through the scene manager. We renamed the button to Close (to avoid misunderstadings) and we added a small note that people should press the Cancel button on 3ds Max Render Window, which will stop it properly.
Regards,
Peter
