Something strange happens to me. I have this simple structure:

MikeFontThn.otf ---> MikeFont -- Thin (menu appareance)
MikeFontRegular.otf ---> MikeFont -- Regular (menu appareance)
MikeFontBold.otf ---> MikeFont -- Bold (menu appareance)

When I test them all together, there is no problem at menu name in Illustrator, Photoshop, Word, etc.
But when I only install only one of them, (for example, the regular) the menu appear like my font is:

MikeFontRegular.otf ---> Regular -- Regular (menu appareance)

Whats going on here?

Thanks a lot guys!
