Formatted Text Does Not Transfer Over To Pasted Text

All of the sudden, when I want to copy and paste something in the same document, the formatted text (whether that be a certain font or bold) does not transfer over to the pasted text. For instance, if I wanted to copy the following bolded word word and then paste it anywhere else in the document, I now get this: word (without the bold). This applies to other cutting and pasting problems: this applies to other fonts and formatting (bold, my Greek font, etc).One more example: before today, if I wanted to cut a text out of my New Testament Greek program right in the middle of a paragraph, the Greek font (or whatever font) would paste normally no matter what font the target MS Word text was in.
