[h-e-w] cua.el and clipboard

[Maurício]

  Hi,

  In windows, I understand that the default Emacs behavior is to 
interact with clipboard. I think this is bad because, when I select some 
text, Emacs kills what is already on windows clipboard.
  I'm now using cua.el, and I like it. Is it possible to tell cua that 
I want to be able to interact with the clipboard using C-C, C-Z etc. but 
except for that Emacs should never touch or use the clipboard?

  Thanks,
  Maurício
