Absolutely not! I am saying that it is unreasonable for MS Word to do
anything other than abort if the user provides a false path in the open
dialog. What is the programmer supposed to do? Is he supposed to attempt to
find a file whose soundex is similar? That would be unreasonable. There is
no reasonable contigency and it's obvious that user intervention is needed.
This situation is asking for an exception.
