Just an FYI type of thing. The problem in opening was simply a delay while the Mac Flash was opeining the PC Flash file. The file consistently took 4 minutes to open/translate on two different workstations (and they're not speed slouches either) Why? I don't know. The file was 9M though. The symptoms look liked a crashed application though; the clock stopped keeping track of time and no disk activity for about 2 of the four minutes. At the 2 minute mark, the progress clock started functioning again and the disks started activity again. However, the system clock on screen remained inactive until the file was completely open.
