This is a worthless program. It is clunky to operate and it's own "help file" will not open from the program button, and looks every bit to be a BETA version of a program that never really should have been sold retail! The help PDF file has it's problems... translated from German with many semantic quirks.Biggest gripe I have is that it does not edit existing PDF files, (which is the only function I wanted) and you cannot even select text to be copied to your clipboard!If you want a program to make PDF files, then just go to http://www.primopdf.com/ and download a much better program which is free.Amazon you have disappointed me by offering such a low quality item. I shoulda' know better.
