OK. I just copied an old application (Civ 2) off of my parents iMac and transfered to my iBook by way of a Lexar jump drive, which I have mainly been using to transfer PDFs and such to/from my work computer (a PC) and my home computer (an eMac). I never formatted the jump drive because when I first stuck it into work computer (PC) it worked fine. I then stuck it into my home computer and I could copy the PDFs to and from the drive fine. Anyway. The copy of Civ 2 I just made now shows up as a Unix executable instead of a classic application. I assume that something is screwy in how the jump drive was formatted for PCs by default(?), and things have gotten confused between the three operating systems: Windows XP on my work computer, OS X on my computers and OS 8.6 on my parents computer. The important question is: how can i convince my computer that this is in fact a classic application, not a Unix executable, and start playing some Civ 2?
