David,
The code runs to completion in six minutes in this case, but when I put it
in a MessageTally it hangs the VM after a while. Doesn't appear to be a
simple case of not enough memory, although, from the Activity Monitor
samples, it does appear to be concerned with memory in some fashion. I'm
working on pruning down a snippet.
Cheers,
Bob
