IECUSTOMIZER
Hi Jandost,
You use a named frame as your target value in either your link or window opener script. eg
<a href=http://www.website.com/aPage.aspx target="MyPage">Open my page as one instance</a>
<script language="javascript">
window.open('http://www.website.com/aPage.aspx','MyPage')
</script>
<noscript>You need scripting enabled in order to use this web site</noscript>
There are also the 'hidden' named targets of '_main',( FF equivalent is '_content'), '_top', '_self', '_search' and '_media'(<=IE6 only) and '_blank'. Note that if you use a '_blank' target, IE7 will decide how to open the window depending upon the tabs and popup blocker settings.
Tabs are no different to windows, each tab is a container for an 'Internet Explorer_Server'.
Regards.
