Actually, I meant what I said more literally than that: I meant work
from a separate list that gives access only to the fonts in that list,
without deleting any fonts from the computer or from Windows's normal
purview. That's why I analogized it to the Library.
If such a thing existed, it might be a third-party program written by
somebody who shares your frustration...
I've not tried it, but the spec sheet for Extensis' "Suitcase Fusion 3"
product (US$99) looks like it might be what you're looking for. It's listed
as supporting XPSP3, VSP1, and Win7, both 32-bit and 64-bit (apparently as a
32-bit application, not native 64-bit).
