I cannot reproduce the problem if I click the search button on the form with the moase to submit it, only if i use the enter key to submit the form does the problem occur.
This is an issue with IE and forms that contain only one item. When you click the enter button to submit the form, the submit button is not included in the form post values.
the search server behavior uses the submit button as the trigger.
The work around is to edit the search behavior to use the text box as the trigger instead.
on the results page, change:
php:
if ((isset($_GET["Search_x"]) && $_GET["Search_x"] != "")) {
to:
php:
if ((isset($_GET["S_ProductName"]) && $_GET["S_ProductName"] != "")) {
