How to cancel/void an order

[Mauricio Tavares]

	This is an easy question but I am completely confused: how do I 
cancel/void and order? What I have noticed is that when you select an 
order in the order manager that might have already be validated (or 
not), and you have *not* captured it yet, it will show a [Cancel] button 
just before an [Authorize] and a [Capture]. That [Cancel] button seems 
to call document.CancelOrderPaymentPreference_10011.submit().

Once the capture is done, the [Cancel] and the [Authorize] buttons are 
gone. Now, there is also a [Cancel Order] button on the top of the 
screen (close enough) at all times, which then calls 
document.OrderCancel.submit(). Pressing either cancel buttons does not 
send a void (or any transaction for that matters) to the payment 
gateway; it is only removing the selected order from the list shown by 
the order manager. That does not make sense to me.

So how will the customer get his/hers/its money back? I tested that with 
authorized.net and pccharge (using the patch created by Marco Risaliti) 
and they both behave the same way.
