Hi Michael Daniels,
Well, it sounds to me like you're trying to make them both your default browser? I'm a little confused by what you've written.
Anyhow, there's an easy fix (just make sure you follow these instructions accurately). First, click on the 'Start Menu' and type in 'Default Programs'. Hit 'Enter'. Click on 'Set Your Default Programs'. Click on 'Internet Explorer'. Click on 'Set This Program As Default'. Then, select the appropriate extensions and protocols. Hit 'Save'.
Let me know how this goes!
