SYMPTOMS
In Windows Vista, the preview window that displays video from a camera device no longer works after you wake the computer from sleep. The preview window may stop responding. For example, this problem may occur if you preview the video from the camera by using a program such as Windows Live Messenger, and then you put the computer put to sleep while the video is still playing.

This problem occurs if the computer is configured not to require a password when the computer wakes up.



WORKAROUND
To work around this problem, set the Require a password on wakeup option to Yes. To do this, follow these steps:
 * 1) Click Startvistastartbutton.jpg], type Power in the Start Search box, and then click Power Options in the Programs list.

If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
 * 1) Click Change plan settings, and then click Change advanced power settings.
 * 2) Click Change settings that are currently unavailable.

If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
 * 1) Expand Require a password on wakeup, and then select Yes in the Setting box.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
