Sure, I shall create an account and send you information on it that is
needed to - login most likely - or something else is needed? I was using
Assembla for my projects before, so I do not think this should be difficult.
As soon as the scripts will be at least somehow usable we shall discuss how
to implement conditional install of them in the appropriate folder of the
screenreader - I am now studying WIX for my own projects installations so I
believe it will not be dificult to add the installation in case of the
screenreader XXX or screenreader YYY is found in the registry.

Ok, I shall install and try the last one I shall find.

Ok, in any case if you are making changes to the class it is better to
subclass it then to superclass it to have the same window class that is
familiar to the screen reader then to change it to a new one.

Does this mean that I shall be able to take this information from the
accHelp property?

Thank you.

Serge.
