Centos 5.6 guest hangs virtualbox when shutdown

[kenyee]

When you ask a CentOS 5.6 guest (64-bit) to shut down or reboot, it hangs Virtualbox (host is Windows XP).
I'm using the latest Virtualbox 4.0.10 and installed guest additions.

Copy/paste to Centos also fails, but only hangs for a little while.

Debian (sid, 64-bit) seems to work fine as a guest in VirtualBox though...no problems rebooting at all

ok...fyi, shutdown works if you do it from the command line, but not if you do it from within KDE which you started via startx....
