Ciao ragassuoli ho questo codice:

codice:
<script language="javascript">

/*
Auto center window script- Eric King (http://redrival.com/eak/index.shtml)
Permission granted to Dynamic Drive to feature script in archive

*/

var win = null;
function NewWindow(mypage,myname,w,h,scroll){
LeftPosition = (screen.width) ? (screen.width-w)/2 : 0;
TopPosition = (screen.height) ? (screen.height-h)/2 : 0;
settings =
'height='+h+',width='+w+',top='+TopPosition+',left='+LeftPosition+',scrollbars='+scroll+',resizable'
win = window.open(mypage,myname,settings)
}

</script>
E la apro con questo link:
codice:
<a href="finestra.htm" onclick="NewWindow(this.href,'name','350','300','yes');return false">
Ho un problema: Come si toglie la barra dove compare l'url?

Grazie in anticipo per l'aiuto e buona domenica a tutti!
