<div>Hi,</div>
<div> </div>
<div>I'm trying to use the htable module, but experiencing some strange behaviors.</div>
<div>When I add an element with hash key 0 or 1 to the table, it does not get inserted to the table; only the element counter is increased.</div>
<div>Any idea what is going wrong? Test code below...</div>
<div> </div>
<div>Thanks.</div>
<div> </div>
<div>Kind Regards,</div>
<div>Zoltan.</div>
