Brian,

Give it a go, but I will be surprised if it helps.  I checked the length 
of my test string being passed to StringToFile and it was reported as 
being the correct length, with no room for the trailing 0 char.  That's 
why I postulate that the issue is buried somewhere in the interface JAWS 
makes with COM.

Cheers,
Andrew.
