(Grrr) That keyboard thing's been giving me nothing but trouble
lately! Yet it doesn't seem to have anything wrong with it... how
wierd...
Anyway, could you possibly send me your source, so I can take a look?
A zip file, MIMEd or UUENCODEd, would be nice if it's more than a
couple of pages.
I'll run it on my machine and see what happens, it may be an artifact
of your setup (which will make it REAL hard for me to debug, as Volker
Oth is still finding out :-)

Hmmm. Look at the testhw.c file to see what I do there - that's the
level of acknowledgement you need to perform.
