Does anyone use FrogFax? It's free and can be downloaded here. http://www.frogfax.com/modules/spxdownl ... .php?cid=1 However, after installation on XP, I was never able to preview the PDF fax file, the program always complained that it can not find the PDF file. Did a local machine install http://www.frogfax.com/modules/spxsecti ... ?itemid=13. And configured RedMon as illustrated here http://www.frogfax.com/modules/spxsecti ... ?itemid=15. Ghostscript has been configured exactly like pictured. I even installed standalone Ghostscript 8.6.4, but it did not help. The fax postscript .PS file was created under \PS directory , but the .PDF file was not and when I clicked Document Preview button, it can't be found in \PDF directory. The FrogFax client looks excellent, and I would really like to see the Document Preview work. Anyone able to share his experience with FrogFax? Thanks.
