On a computer that is running Windows Vista, some Help topics in Windows Help and Support include hyperlinks. When you click the hyperlinks, additional text is displayed. For example, the additional text may be the definition of a term or the reason for an error that the user encounters. However, Microsoft Narrator does not read the additional text after you click the hyperlinks.

On a computer that is running Windows Vista, you move the focus between folders. When you do this, Microsoft Narrator may not read the detailed information about a folder.

Note: When this problem occurs, Narrator does not notify you that a folder is empty.

When you use a screen reader program, such as Narrator, to read screen items in a WebDAV location in Windows Vista common file dialog boxes, you experience the following symptoms:

• The screen reader program may read the contents of a dialog box one time, and then the screen reader program no longer works. If you press TAB or SHIFT+TAB to move the focus through elements in the dialog box, the screen reader still does not work.
• If you close and then reopen the dialog box, the screen reader again reads the dialog box items one time.
  You experience this problem if you open a common file dialog box to a WebDAV location.

Note: WebDAV is the set of extensions to the HTTP protocol. WebDAV lets users collaboratively edit and manage files on remote Web servers. Microsoft Office SharePoint Portal Server is an example of a WebDAV location.

In Windows Vista, there is no option to control the volume when you click to select the Hear text on screen read aloud (Narrator) check box in the Ease of Access dialog box.

Additionally, internal speaker controls may not change the narrator volume level. These controls include volume controls on a multimedia keyboard and Fn keys and volume knobs on a portable computer.
