Martin,
The largest objects I've needed to work with in AS have been DVD image files
greater than 4 GB in size. I suspect that the crash log entry is a red
herring: that it is in fact Image Events that is causing the crash and
returning a misleading error to the AppleScript script that owns this
particular instance of the process. Problem 1 only reinforces my suspicion.
