To maximize the width of the message preview pane in Netscape or Mozilla:
- Select Edit | Preferences... from the menu.
- Go to the Mail and Newsgroups category.
- Under General Settings, select the right window layout, which trades a smaller folder list for a bigger preview pane.
- Click OK.
- Close and reopen the mail window.
Note: In Netscape 4, the preview pane layout setting is under Mail & Newsgroups | Window Settings.
