Mail Merger issues with Office 2003

[Jim]

I use an Excel template to do a query from a Remedy database and then
use the Mail Merge feature of Word 2003 to pull the information from
the Excel sheet into Word.

This works fine under Office 2000 but some/most of the information is
truncated when run under Office 2003. Does anyone know if this is a
bug in Word 2003?

I've run it on a system with up to 1GB of memory and still see the
problem but when run on a system with Office 2000 with only 512MB of
memory, the merge functions as expected.

I can't share the data as it is proprietary.
Thanks,
....Jim
