Question:  Can PC FrameForge files be opened on a Mac running FrameForge? And Vice Versa?

Answer:  Yes, if you use bit of care with the file format. Go to the preferences dialog in FrameForge on each machine, click the File Format tab, and make sure that the default file format is set to something other than "Windows ONLY" or "Mac ONLY".
