If you're using PFE with Windows NT or Windows 2000, you may find that the Monotype.com font, although being fixed-pitch, is not selectable within PFE for either a screen or a printer font.
The problem is that the font file contains incorrect control information, causing Windows NT not to offer it for use to any application like PFE that asks specifically for fixed-pitch fonts.
A corrected font file is available from the Microsoft Web Site
