I have a questions about the difference between Brf and Dxb. What is the difference and if you're going to put books on the Web as, say, web braille, they're Brf so how do you save a document if you've had it in Duxbury as a dxb file? My boss asked me to check on this. I'll be away after 11:30 today, want be back until Tuesday, but I'll look forward to any info then. Thanks, Deb B.
