Select View|Character Encoding|Customize... in the MailNews main window or in a Compose window. Result: Nothing happens. Expected result: Open the Customize Character Encoding dialog. Reproduced with a CVS build from yesterday and build 2004022509 on Windows. I don't know when this regressed, because I haven't selected this dialog for a longer while, but I know this worked once. ;-) View|Character Encoding|Customize... from the Navigator window still works.
