I’d already resigned myself to the constraints: I’ve got multiple VirtualBox VMs going, each one with a different font variant loaded. 
But if you don’t mind taking the time to help me thought a fix, I’d appreciate it. You should be able to get me at office >at< bootstrap-it.com
Thanks!
OK. I will make some font families for you to test and send them there.
I know I can make it work by essentially making all the fonts separate typographic families.
Then Book, Medium, Light, etc. are as different as Gotham vs. Courier.
So no more multiple VMs.
But there some other less severe configurations that I would also like you to test for me.
Ok. I’ll keep an eye out for the emails.
Thanks,
OK. Sent the fonts all configured as separate families.
Let us know how it goes.
