The secret to closing the window without having a confirmation message appear is to name the new window and then have the window that created it close it.

Window A opens Window B and gives it a name (e.g. windowB);

Put a function in your calling window that closes the window you opened (e.g. closeChildWin). Put a function in the page that serves as the response from your cgi program.

function in Window A

function closeChildWindow()

{

windowB.close();

}

function in Window B

function pageLoad()

{

// Call this onLoad function onLoad

parent.closeChildWindow();

}
