Hi,

Now I am not able to reproduce that issue currently .

By the way :

I debuged your page, and found something special. 

the form code is :

<form name="form1" method="post" action="sh2352_historia.htm?%2fsh2352_historia.htm" id="form1">  

Maybe that cause the issue.

I will do more tests to find the reason, and will provide a solution in 24 hours.

Regards,
Terry
