Shawna, there are a number of ways to do this. If you are in the ledger, press F9 to edit the patient. If you are in the patient, press F7 to bring up the ledger. Once the windows are brought up, you can press Alt-W and then 1 to switch between the windows. Another way to do it is launch Medisoft twice and press Alt-Tab to toggle between the two instances of Medisoft.
