I noticed a strange activity in my magento site. I checkout using paypal then I was redirected to their gateway payment page. Then from there I decided to go back to the site by pressing the back button of the browser. I was now back in my checkout page then I decided to checkout again using paypal, I was redirected successfully to gateway payment page.
What is strange is that I get two order records in magento backend, instead of updating my previous order. Is this normal or not? Thanks!
