FoxPro 2.6 compiling refers to “phantom”

I have seen this problem come and go around the office and have never found a solution to the problem. If you compile on a system with a c and d partition or a c and a cd-rom, when you execute the app, you are asked to put a cd in the tray. You can insert any cd and it will get you through the problem. If you compile on a system with just a c drive, you don’t have the problem. We have used several rom burning programs and see this problem manifest itself with all of them. For the end user this is extremely irritating and looks like bad programming to us. Any help would be much appreciated…
