Why do some fonts in the CG default to italic, even though they are not designed to be italic by default. I.e. they become italicized in CG even without the italics button being engaged, yet in any other windows app, they are not italicized unless you set them to be so accordingly. This happens with several fonts on the system in question, including:

Bitstream Vera Sans
Eurose Wide Heavy
Futura Md BT
Franklin Gothic Book
