Supports most Flash 2 features and a few Flash 3 features plus comes with a standalone Flash viewer that doesn't require a Web browser. Although somewhat buggy (in some situations, it may crash your browsing session) and having no HP-UX sound support, it's a major addition to the browser plug-ins available for HP-UX. Note this is not an official plug-in from Macromedia - it was developed by a third party initially for Linux. If compiling from source, you must use gcc and g++.
