It is common for users to use the pop out window when using multiple screens. So for example the purchase invoice on one screen and vendor info on main client on the other screen. If the user completes the invoice and selects post and new, the new invoice opens in a new browser window and leaves a blank browser window still open. If post and new is used, does it not make sense to consume the same browser window or auto close the posted one. We have seen cases were after processing the user has 20 plus windows open.
