Alt Gr+a

[Gerhard]

I created with MSKLC a custom keyboard. It is essentially the US keyboard
with German ä at Alt Gr + a, etc.
But when I use Alt Gr+a with this keyboard in MSWord 2000 strange things
happen: Sometimes I get ä, sometimes I can not type at all, sometimes the
document is duplicated.
How can I turn off these unwanted Alt Gr functions in MS Word 2000.
Thanks in advance, Gerhard

To be more specific the custom keyboard should write for:
Alt Gr + a = ä
Alt Gr + o = ö
Alt Gr +u = ü
Alt Gr + s = ß
Shift Alt Gr + a = Ä
Shift Alt Gr +o = Ö
Shift Alt Gr + u = Ü

Alt Gr + a = ä, Shift Alt Gr + a = Ä, Shift Alt Gr +o = Ö, Shift Alt Gr +
u = Ü seem to work.
Alt Gr + o = ö and Alt Gr +u = ü sometimes write and sometimes don’t
write.
Alt Gr + s = ß most of the time duplicates the document.
