You're not using Opera right now, you're using Netscape Navigator 4.5.
That doesn't necessarily mean you don't also have Opera installed on your computer, but it does mean that you're not using it right now.
If you want to find out what version of Opera you have; open and use it to revisit this page - then we'll be able to tell you what version of Opera you've got.
If you have any more questions, use the contact form - we'll answer it and include it here too.
