Hi,
Maybe you have a javascript issue which stop the updating process in the page.
I think that it would be easier with an access to your store (and some explanation on how to reproduce the issue) so we can take a look directly.
Like usual, for such private information, please use the "contact us" form with a link to that forum thread.
