I may be offbase, but it appears that Hiding Fonts (a great feature!) isn't recognized by other applications. Wordpad (that comes with W7) seems to work as you'd expect. No other legacy app seems to (including Microsoft Word 2007, InDesign CS4, ...). I would have thought that the hiding would basically hide the font enumeration that usually takes place between the application and Windows, but I guess not. Are all applications going to have to be updated to work with the Show/Hide Font feature in Windows 7 RC1?
