Netscape 7.0

I've just installed Netscape 7.0 to give it a try. I've always been an IE person up until now but so far this version of Netscape seems to work very smoothly and I'll stick with it a while.

The only thing I can't do with it is to include the option to edit web pages stored on my hard disk using my preferred web editor (Namo 5).

I've edited the Windows 'File Types' so that if I right click an html file and go to 'Edit' the page will open in Namo. However, what I can't get Netscape to do is give the option of editing a page with Namo from within the browser, as is possible with IE. If I click 'Edit' in the File Menu the page opens in Composer only. IE gives the option of being able to edit pages in Namo, Word or Notepad.

I tried playing around with 'Helper Applications' hoping to make the option come up somewhere but to no avail.

This may just be a case of not being familar with Netscape. Was there a way of doing this in previous versions of that might apply to this one?
