Are your running Vista itelf in Portuguese, or are you using
gretl's language selection mechanism to put the program into
Portuguese?

With Gretl language selection explicit in pt_BR or in automatic
mode the error occurs.
 
What do your "Regional and Language Options"
settings look like in Windows?

My Vista regional option is Brazilian Portuguese.
