Ghost. How are you opening PC files with a MAC? Specifically. How are you able to open .cr2 files generated by a PC? PC's can open any MAC figure's without any special convertion program. You just don't get any .rsr files with a MAC figure. So you'll need to resave the figure once opened to make a thumbnail picture for it. However. MAC's use a horizontal layout for the .cr2 files. And as far as I knew. You can't open a PC generated .cr2 file on them because PC .cr2 files are laid out vertically with a different kind carrage returns. ScottA
