All versions of Netscape Navigator and Communicator, except "Preview
Release" versions, are available in two flavors: a "domestic" flavor
with 128-bit encryption for use in the USA and Canada, and an
"export" or "international" flavor with only 40-bit encryption.
(There is also a third flavor of Communicator 4.x available for use
in France.) Preview releases are only available in the export flavor.
To get 128-bit encryption, you must download the U.S. flavor.
