Hi Dan,

I just wrote my son,  for whom I'm writing this app,  that I was
hoping I'd get a magic bullet so that I didn't have to write my array
of name-changes to disk, read them in in second program and copy in my
change algorithm.

And there's my magic bullet.  Now I have to apologize for falsely
claiming that Windows was at fault :-)

Thank you very much for post such a neat solution.

Best wishes,
Richard
