Product Variations problem

Hi,

I have a problem with products that use variations in WP e-commerce plug-in. When the product is selected and the Add to Cart button is clicked the purchase notification pop up gets stuck on ‘updating’. If the page is refreshed, or another page visited then the item is added to the cart, but this lack of notificatio is causing confusion and problems with customers.

I have all the latest updates installed, and the notification works fine on products without variations. Does anyone have any ideas on solutions??

An example of the product can be seen here: http://www.cheeky-tatz.co.uk/products-page/accessories-and-starter-packs/glitter-refill-bag-blue-15g/

Thanks in advance!
