Return to parent and refresh once?

[azaidi]

Hi there

I open a jscript window in my index.php thus:

echo "<a href=\"javascript: void window.open 'updateinteraction.php?interactionid=$intid','','height=160,width=265,top=200,left=458')\">Link</a>"

In updateinteraction.php which is now the small window, I complete a table update - now how do I close this window and then refresh the originator index.php page? so that there is only a one-time refresh

Thanks in advance
