Sadly the soundfont support in Vista sucks even with that updated modified CD. Sometimes I can't get it to actually load fonts... Of course, soundfont support is completely non-existent without this guy's attempt. Heh. I play old games thru DOSBOX a lot and like to use soundfonts for the game MIDI. XP seems to be the only way to go if you do that.
But otherwise, the apps seem to work ok in Vista.
