[texhax] examdesign package and several correct multiple choice options

[Mauricio Ortiz Calvao]

Hi there,

I am using Latex examdesign package and have come across the following 
"bug": I made a multiple choice examination with some questions having 
several correct options. I tried to type it as, under the multiplechoice 
environment:

\begin{question}
The electric charge 
\choice[!]{is quantized or discrete.}
\choice[!]{is conserved.}
\choice{is always positive.}
\end{question}

However, when I try to generate the answer key it gets messed up, somehow 
like

1. (a), (a)

instead of 

1. (a), (b)

Can this package not handle multiple choice questions with several correct 
answers??? If that's the case, I guess it would not be quite difficult, 
for someone minimally versed in dealing with Latex classes to modify 
its class (exam.cls) file so as to cope with this... The problem with me 
is that I do not understand this minimally...

Any help is appreciated!
