Summary

Hi Marsel, 

This is a low priority thing, but could still annoy a lot of users. 
It seems if a user tries to scrub the timeline during a recording, 3ds max will crash.

I have tried this with basic Lucid scenes and it does not occur. I think it will only occur if the user has a Lucid operator in a  particle flow event. 

I have attached a short video to show what was happening. While recording, if I drag the timeline backwards, 3ds max will crash.
