Flash editor changes font style when I'm done editing text. Suggestions?

Question

I'm using a custom font called "Quint" in a flash file. I have two styles for it installed on my machine, Medium and Italic. I want to use the Medium font. After I type in the text and take the focus away from the text field in the editor, it appears to have gone italic. Why does this happen? It is just classic, static text!
