I'm running Windows 2000. Until a few days ago, when I right-clicked a file in Windows Explorer, my preferred text editor always appeared as one of the choices in the pull-down menu. Then I installed Netscape 8 (will have more questions on this issue in appropriate section!). Now the editor doesn't show up in the pull-down menu and I don't remember how to put it back. It seems to me that it wasn't hard to do, but it's been so long that I am at a loss.
