We have a Drupal site that is currently using the CIM features of authorize.net. However when using the stored credit card feature in IE9 or IE10 it seems to try to process twice. Within the logs of our website the first kickback says "direct response: 1,1,1,This transaction has been approved" then the next one is "ErrorE00027A duplicate transaction has been submitted 3,1,11,A duplicate transaction has been submitted ." This is very confusing and frustrating to our users because they receive a message that says that "A duplicate transaction has been submitted" no knowing that the transaction actually when through. The issue doesn't exist in Chrome of Firefox. Any ideas?
