Search box opening a new window?

[llawrence]

I've got the basic search box script on every page of our site:
<form action="http://www.wolstenholme-int.com/phpdig/search.php" method="post">
<input name="query_string" type="text" class="style1" value="" size="18">
<input name="search" type="submit" class="style9" value="Search our Site">
</form>

But would love this to open a new window or pop up box for the search results instead of jumping from my existing page. Any ideas for a script newbe? Thanks. Louise
