Help window.open, change uri

[Fabio]

Hi All,

I open window by:
<A class="beta" onmouseover="window.status='reset calendar'; return true"
onfocus=this.blur() onclick="window.open('<%= CTX_PATH
%>/calendar/reset_calendar', '',
'width=400,height=350,dependent=yes,location=no,menubar=no,resizable=yes,scr
ollbars=yes,toolbar=no'); return false" onmouseout="window.status=''; return
true" href="<%= CTX_PATH %>/portal/"><reset calndar</a>

Is possible change in new window first window's url?

Thanks for any sugestion.
