I updated from 3.2.8 t 4.0.4 today, and everything was working fine. It informed me that Additions was out of date, so I updated. Everything worked as normal until I restarted the VM.

After that, AutoCAD loaded fine, but when I tried to open a dialogue ('Layers' or 'Open File'), the VM instantly re-started, no errors, no blue-screen-of-death, just Windows starting again.

Downgrading to Additions 3.2.8 fixed the problem. Do I need to change some settings before using Additions 4.0.4 to make it work properly, or is this a bug?

Fedora 14 / VirtualBox-4.0-4.0.4_70112_fedora14-1.i686
Intel Core 2 Due
nVidia GeForce 9400M G

I had the same problem. MacBook Pro upgraded to Virtual Box 4.0.4. Installed New Guest Editions with 3D support (in safe mode) Autocad 2011 opens then crashes Win 7
Rolled back to 3.2.12 and it works again.

I've got a similar post in the Linux hosts forum
