Typeface question/issue?

I hope I’m okay starting a thread for this; I glanced around for an existing thread to put it in but I wasn’t sure where it would best fit. I don’t know if it’s a bug or not.

Whenever I use the typeface “Bookman Old Style,” the text appears to be boldfaced, whether I’ve selected bold or not. In the meantime, I’ve simply switched to Book Antigua.
