Been years. This still happens. And I always forget. Today in Max 2015 SP3 with B2M 3. Please fix this and/or ask AD to fix anything that they might need to do. This issue has caught me off guard so many times as when you are in creative mode dragging nodes in Slate, you are not thinking about OH NO, DON'T DRAG THESE NODES ON THESE INPUTS because you will crash a multi-thousand dollar application. I love B2M, Substance and Max... but jeeezus... I'd like to see this bug squashed.
