R : Many html files on web sites have an extension .html. It is possible that
only the files with extension .htm are associated to your web browser. If that is the
case, select a file of extension .html in the Windows Explorer (for example
calc.html in the directory ROSETTA\ast\websites\alg\calc\web of the CD-ROM)
and double click on this file. This opens a dialog box with a list of programs to
associate. Select your default web navigator or, if there is none, select Nestscape on
the CD-ROM (file ROSETTA\ast\view\Netscape\Program\netscape.exe,
cf. sec. 4.11.1).
If that does not solve the problem, verify the installation of your web browser;
verify if the files with extension .htm and .html are associated to a browser which is
always accessible.
