[h-e-w] can't customize CUA mode on in EmacsW32

[Eric Hazen]

I have just installed EmacsW32-1.56 (patched).  I put
  *(setq cua-mode t)*

In my ~/.emacs file.
After I start EmacsW32, the value of the variable cua-mode is t, but
the CUA keys don't work.  I have to toggle it off and on using
either the cua-mode function or the menu option.

Anyone else having this problem?
