When making changes to command aliases, I've gone to Tools>Customize>Edit Command Aliases , and the acadlt.pgp TextEdit window opens, as usual. I make the changes & close TextEdit, but the changes do not work. I have gone back and opened the acadlt.pgp file, and the changes appear to still be how I changed them. I have tried reloading the command aliases as well. I even looked in the Application Preferences>Customization Files>Command Aliases, and the path to the acadlt.pgp file is correct. All seems fine in appearance, but the new command aliases do not work. Suggestions?
