[AccessD] 32->64 bit

[Rocky Smolin]

I have a module called Publics which has all of my handy functions - like
browse for file, browse for folder, screen resizing etc. I copy it into any
new app I create. Handy.  I have another one that has the back end
relinking  routines, which I use in almost all my apps. Ok used to use.
I'm on my last two clients.
