"Bootcamp.exe -StartupDisk" no longer functions under BootCamp 4?

Hi all,

We've been using this command on our Macs here to set startup disk to Mac OS after our automated image process completes (We use Casper).

Basically Windows 7 is the last OS to boot and after its automation is complete it tosses the user back to OSX. Problem is this command used to work but seems to have stopped in the latest build of Bootcamp (WindowsSupport files from a MacBook Pro 9,2)

c:\progra~1\Bootca~1\bootcamp.exe -StartupDisk

Here is a KB article discussing the command: http://support.apple.com/kb/HT3802

Anyone else seeing this? We're using the 32-bit version of Windows.
