Vista x64 problems with CD/DVD drive

[frg]

Because of the (now fixed ) bug in the earlier 4.3 versions where a SATA CD would hang or crash the VM I moved the CD/DVD drive to an IDE controller. This still works for Vista x86. In 4.3.8RC1 it now will hang the VM if you insert or remove the virtual CD in Vista x64. I can reproduce it just mounting the guest additions. VM Window becomes unresponsive and can not be closed. If I try to kill the process via task manger an error message about suspend is shown. It's also in the log. After dismissing the message the VM works again and can be used normally till the next mount/unmount.
