Keeping windows on top

By default, most Help windows temporarily close from view when users select other windows (such as windows for applications that are running). You can specify to keep windows always on top. When this feature is enabled, the Help window is the top-most window on screen, regardless of the active window selected by the user. This is especially useful for Help windows because users can view topic content (such as numbered steps for a task) while they are doing the procedure in the application.

To specify a window as always on top:

  1. From the File menu, select Project Settings.

  2. Click the Windows tab.

  3. Select NewWindow (the default) or the name of the custom window you designed for the project.

  4. Click Properties.

  5. Click Advanced Properties. The Advanced Window Properties dialog opens.

  6. Click the Extended Styles tab.

  7. Select Top-most Window.

Tip: To test this feature, compile the Microsoft HTML Help system and run the .CHM file. When the HTML Help viewer opens, select another window that is open on your system. The HTML Help viewer remains the top-most window.
