I am now using Insightbb as my e-mail client v. yahoo in the past.  I can't get windows XP to recognize its presence to use as the default e-mail source.  If I go to (Internet Options/programs) InsightBB is not listed among the options.  I am given the options of 1. Outlook 2. Outlook express 3 Hotmail and Yahoo.  How do I get Insightbb listed?  I use Netscape.
