In MHO having to highlight the FL you wish to change the name to before the a][e button is activated is not very ergonomic or intuitive. I allowed the mouse pointer to rest on all the buttons looking for a button that would allow me to change the name of a FL but none was found since I did not have a FL highlighted. So, I renamed the FL in Windows and imported back into Sentinel.Any chance you could be talking about the a][e icon on the third row of the Sentinel Home page? Highlight the Favorites List whose name you want to change, then click on that a][e "thingy" and away you go.
