When I am trying to record an action, the following is happening:

I set all the recording options, started recording, specified the URL as I have to record the actions in a website.

The URL opened in the browser (Netscape 4.7) specified in the options. It is opening but before the page is fully loaded the tool says "Illegal operation performed" and I am forced to close it.

What could be the problem?

The default browser on my system is IE 6.0. when I set the option as default browser it is not accepting IE and Netscape 7.0 by saying it is not existing. It is accepting only Netscape 4.7 that too when I specify the path of its location. How can I change this to IE/Netscape 7.0

Thanks in anticipation
