Thanks for the flattering comments, Colin. I hope we can lure you into other sections of the magazine in future!
If you have more than one browser installed on your system, the default browser is the one which launches when you double-click on a filename with an HTM or HTML extension.

Click Yes to go with Netscape

Click Yes to go with Microsoft

The installation routines of Navigator and Internet Explorer stop short of offering to delete a rival product found on your system (though I suspect they'd like to). Instead, they present a dialogue box which gives you the option of making the new browser your default. It is possible to "turn off" these dialogues so they don't reappear, but it's quite easy to revive them. If Internet Explorer is your default browser, and Navigator doesn't prompt you to change this when it launches, try the following proceedure.
Run the Registry Editor (regedit.exe) and drill down through the HKEY_CURRENT_USER branch to \Software\Netscape\Netscape Navigator\Main. Double-click the Ignore DefCheck key and change its value to no. Next time you start Navigator, you will be given the opportunity to restore Navigator as your default browser.
If you have the opposite problem, and wish to make Internet Explorer your default browser, you can do this without the aid of regedit. Fire up Internet Explorer, choose View--Options? and select the Programs tab. Make sure that the Internet Explorer should check to see whether it is the default browser option is checked. When you restart it, you'll be able to re-establish MSIE as your default browser.
