FontBook makes warning when installing font ...

[Morten]

Hello,

I have made a really large font with some spray-effects. The Otf font-size is 4,2 MB. 

When I use FontBook to install the fontfile, a warning appears: Dont use this font, 1 fatal error was found. (System approval don't like the font!)

If I install the font, ignoring the warning, it works fine and without any problems. 

So: How can I prevent that FontBook gives that warning? Thanks in advance for helping.

Regards,

Morten
