AbleCommerce Shopping Cart Software

We switched from drop downs to buttons for shipping options. Now we are getting some emails that they are getting a shipping error message that says "The order could not be completed and your payment was not processed, either a selected shipping method is no longer valid or selected a different method"

If they click off USPS and onto another option then back on it works. Obviously, 99% won't unless I am on the phone with them.

The issue was IE7 but could be others.

Any fixes for this?

Thanks
Mike
