Strange cart bug
I have been testing my site, and I have just found a very odd bug or behaviour.
If I add two products to my cart, click on the remove box for one of them and update the cart, it then removes that one product leaving me with one left. OK so far, but if I then click on the 'More info' link of the remaining product to visit its detail page, THEN click the back button, the cart removes the one remaining product!
I have also done this to a cart with three or more products, remove one product, click on more info of a product left in the cart, click back and the cart holds one less product again! It's actually deleting the product I have just visited and clicked back on. The browser asks do I want to send the form again?
Why is it removing a product that I didn't check? I assume there is some sort of session issue happening as there is nothing showing in the browser address bar.
