The black screen is a safety feature - Windows has switched to a secure
desktop so that the dialog box cannot interact with the desktop or other
open programs. This is a feature that can be turned off in the Registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\PromptOnSecureDesktop
1 for on, 0 for off.
You can also change this using SECPOL.MSC if you have Vista in either the
Ultimate or Business editions.
