For those who might find it useful, it turned out to be a specific font issue. The problem is resolved by changing the font name in class “StdFonts” which is used during runtime.
Ui()
{
return OSVersion() < OSVersion.VISTA ? "Tahoma" : "AngsanaUPC"
}Since I am using Windows 7 (64bit), “AngsanaUPC” is what is returned and used. But this change also affects everything else across the whole interface which is not what I want. They are still readable but barely. Could I define font per column?
