nvform.php - success page query

[Franco50]

I have created a simple online form for a website using the nvform.php script but I would like the 'success' page to open in a new window, where I will have a 'close window' javascript:self.close() function. The line of code in the mailform file which redirects to the success page is:

<input type="hidden" name="success_page" value="http://www.borderdesign.co.uk/new/thanks.htm">

Is there some overwhelming reason to open a new window. Most users, I suggest, would find this annoying.

You expect a thank you page to open in the same window you are already in.

You need to think of accessibility issues. If I'm a user who cant see the screen, how would I know what you have done?
