This issue affects sculpt meshes created with WW versions prior to Version 2.82. New sculpt meshes do not have this problem.

When you close a scene with a sculpt mesh composed of thousands of displacements, Max becomes unresponsive and appears to close. This applies to the following actions if the current scene meets the above condition:

• Closing 3ds Max
• Opening a File
• Creating a New Scene

The exact cause of this is unknown, but Max is not actually frozen. It appears to be frozen, but there is some kind of slow memory re-allocation going on. Max will eventually respond.

Usually, in this case, it is faster to bring up the Windows task manager, kill the 3dsmax.exe process and restart 3ds Max.
