Greetings for the New Year! Down to business... As a recent switcher, I work between my 12" PB and a PC. Today I discovered that the CD I burned on the Mac was not receognized by the PC (this is the first time I'm transferring files this way). It's a multisession CD that I burned, which has .jpg and .pdf files. Is there something I have to do when I burn the CD to make sure it is PC compatible, or is this not a normal occurrence? Thanks very much for your help!
