Hi Nanci,

I'd also like to make sure nothing else is amiss, as I was unable to reproduce the error in my testing environment, only on the server after waiting through an hour and a half of processing.

One question and a SWAG:
Could there be a difference in your error handling in your test environment and on the server? (ON ERROR...)

Is the setting of Talk different? Something about talk and overflows jogs my memory, but I can't put my finger on it right now.

BTW, I work in Naperville, "neighbor". Who do you work for?
