Mistakes

Mistakes happen, however careful you try to be. Because of this we provide the replacement files for the web pages to correct the mistakes.

One saves the source of the document by using the popup menu that Netscape Navigator or Internet Explorer provide for the links. To activate this popup use of the right mouse button in Windows while for the Mac OS one click and hold the mouse button on the link, then:

• Netscape Navigator : from the popup menu select "Save this link as...". In the file selection dialog that will be opened, do not change the name, but select only the folder in which the file is to be save. For the Format popup select the option "Source", and click the "Save" button.
  
• Internet Explorer : from the popup menu select "download link to disk". In the file selection dialog that will be opened, select the location to save the file and click the "Save" button.

It is prudent to first make a backup copy the files that are to be replaced.
