FrontPage Include files are ordinary html pages that are included in
other pages. They can be opened by double-clicking in the folder view
or folder list., or by:
opening a page containing an include
Right-click anywhere within the included area
choose "Open page in new window" from the right-click menu.
Note that FrontPage includes must have a full set of HTML tags:
<html>
<head>
</head>
<body>
</body>
</html>
or they will not be included in the pages, and may not open in Design
View.
If the includes are ASP includes or SSI, these must not have the HTML
tags mentioned above.
FrontPage will not open a page in Design View if the code in the page
contains errors that FP may attempt to correct. This is often the
case where the includes are badly designed.
