mailto problem

[pelegk1]

i am doing this

str="ìòéåðê - îñîê îàúø ìàåîéú-ðè";
str2="mailto:?subject="+str +"&body="+parent.location;
window.location.href=str2;

now when the mail message open's
everything is ok exept to the :
parent.location

the problem is that in the url line it written :

http://myServer/Home/menu/sub_frames.asp?
source=&DocID=903

but in the mail it only show's :

http://myServer/Home/menu/sub_frames.asp?source=

why is that??????
