Interestingly, I am having the exact opposite problem when I process Credit Card Payments in QBO. My screen now defaults to "save and new" which is useless when completing this task and it takes me to a blank payment screen instead of closing and going back to the list of open invoices like it used to. Haven't had this problem in 5 years. It appeared around the same time as this, and it's awful! I feel the reverse side of your pain.
