Hi all
I am digging up this topic because I have the same frozen timeline problem, and this on the different versions of 3dsMax that I have installed over time. On the 2023 it is also the case, but I do not think it comes from Corona.
As a reminder, when you move the cursor of the timeline, whether or not you are in autokey, 3dsMax freezes completely for at least a minute.
For all intents and purposes, if anyone has found a solution to this problem, I'd be happy to share it with us.
