ordering products online?

[Bruins Fan]

Hi Everyone,
I tried to order something online today using my macbook, but  
encountered a problem when I was directed to the secure site where I  
needed to enter my credit card information, etc.  I couldn't interact  
with the HTML content or get VO to read it.  I had to resort to using  
my windows desktop to get what I needed.
This has happened to me once before.  I know that VO won't read things  
like passwords, so I'm curious whether the same thing applies to  
secure sites where things like creditcard numbers are required.  Is  
there a work around for this?
Thanks, Olivia
