Hi Fred,
>I found one significant difference to other fonts. This is an 'O' for open Test instead to True Type
That's OpenType. Most Windows font's are actually OpenType these days. The only reason I can think if why you get an incomplete list of fonts is that VFP somehow assumes it needs to use a different font script or code page. I would imagine that VFP would filter out fonts that do not support certain scripts. However, aside from the Windows installation, the Codepage setting in the Config.FPW and the FontScript property I wouldn't know how to make VFP switch to a different script.
