Netscape weird behaviour !!!!!!!!!

[rawatds]

I am using PL/SQL cartridge for my web server application.
I am using one particular instance where i am directing my user to mail me if they want the access to a particular
application.

The PL/SQL syntax is :

For Netscape is as follows :
===========================================================
htp.p('var sn="<A HREF=''mailto:'
||'mahesh.k.gupta@xx.com;dharmendra.rawat@xx.com'
||'?subject=The link is below to access '||UPPER(cookieparam)||' ''>Click here to view example email</A> -'
||' copy these details to your normal email program (Outlook) and send in the usual way'
||' (as you cannot send a XX email from Netscape Communicator)";');
===========================================================


For Internet Explorer the code is :
===========================================================
htp.p('var si="<A HREF=''mailto:'
||'mahesh.k.gupta@xx.com;dharmendra.rawat@xx.com'
||'?subject=The link is below to access'||UPPER(cookieparam)||' ''>Click here to send email from Outlook</A>";');

===========================================================

In both code the mail id i.e.
mahesh.k.gupta@xx.com;dharmendra.rawat@xx.com
is given and when user is clicking the link given
,in IE it is working fine and coming as

mahesh.k.gupta@xx.com;dharmendra.rawat@xx.com

but while thru Netscape the mail id
are not dispalying properly
instead it is coming as
"mahesh.k.gupta\"@xx.com;dharmendra.rawat@xx.com"

Can anybody please tell me the difference why it is coming
and please tell the remedial action in the code .

Thanx in advance
