I'm using authorize.net - just normal AIM method.
Normal validation errors are fine, but if it the client side validation passes and it goes to the processor and the processor throws an error the error is displayed on the /cart/checkout/review page.

Not sure if this module is the proper place to report this - seems like everyone would want the errors to redirect to the /cart/checkout page so that the user can correct the error, right? Whether they are using this module or not...

Any ideas?
