I have a customer who needs to start adding attachments to the notes section, but the option is grayed out. The only thing I can think of is if this is a feature not supported in the BV Standard Edition which they're using? 

If I look at a BV Client-Server Edition then in notes beside the new button there is a drop down button which gives you the option of 'New note' or 'New attachment'. But I don't see this when I look in the BVSE company, it's just a single button and I don't see a way to add an attachment to the note.
