Fellows-

When I had a Mac, I used omnigraffle to create some files, saved as .graffle. Having fallen from that state and currently using vista (Alas!), I found the files in the backup I made of my old computer. I would like to access them again, as they were quite pleasing (thanks in no small part to the program in question!). However, their format appears incomprehensible to the windows based picture viewers I've tried (paint, adobe, & a few misc.). Is there any way of recovering these files, short of finding a mac with the program on it and saving them as something else?

Thanks for the help,

Thomas
