I made a cut-down version of my Verajja font for use on a PDA. It has only 905 glyphs instead of 1742. If I view the font in MainType, the Info pane shows 1742 glyphs and the missing glyphs are displayed in the characters pane. Obviously, MainType is displaying the installed font, not the selected font. I opened the font in FontCreator from MainType to check, and the font does indeed contain only 905 glyphs.
That is a Windows 95/98/ME limitation. This should work just fine with more recent versions of Windows.
Thanks.
