[h-e-w] EmacsW32

[Mário Barbosa]

Hello,
I installed EmacsW32 (after downloading and executing
Emacs-23-CvsP091103-EmacsW32-1.58.exe).

I accepted all the default installation options.

I did not customize anything.

I am using Windows XP home edition (portuguese).

Problem:
When I start a new file or open an existing file (extensions  .txt or .c), I
am unable to type square or curly brackets like {[]}.

These characters are usually typed pressing Control+Alt and keys 7, 8, 9, 0
but this does not work in EmacsW32.

If I open a file which already contains these characters, they will be
displayed; but I cann't type new ones.

Is there any way that I can solve this problem?

Thanks,

Mário Barbosa
