Internet Browser Switching
Dear  [Lynn],
Well, at first thought, it occurs to me that you can reinstall Netscape. This will reset your default browser to Netscape. However, it will probably take a while to download if you don’t have a local copy.
Another option is to purchase a browser switch utility at:
 for $20. There’s probably a cheaper solution than this however.
There is also the option of directly editing your registry. However, I’d need to ponder this one a little, to minimize the chances of corrupting your registry and rendering your computer useless.
Will think about it and run a few tests here, and get back to you.
