I have several friends who have used PC Quilter, but they seem to have moved away from it and are using other programs now. I have *some* knowledge, but am not confident enough in my limited knowledge to pass it on to you with certainty that my information is correct.
However, there IS a PCQuilter group on Yahoo that may be able to help you with your questions.
