Hi Bill, I have been a long time user of PAF and read this forum often. You are right about Dropbox, it is useful for synching PAF on multiple computers. The only draw back I have discovered is that on the two computers I have linked my Dropbox location is different. When I copy my Home PAF directory to Dropbox I can run Pstart.exe or Paf.exe from my Work Dropbox but all the references to the graphics files for each person are wrong as they still point to my Home location. If you just run the program there is no problem.
