I am noticing that if I close PL/SQL Developer with saved files open and then I got to reopen the applications it automatically opens those last open files. Is there a way to turn this off? I am not always connecting to the same database so it is frustrating to have the files open on the wrong database and have to close them. I also noticed that If I then right click on PL/SQL dev from the task bark to launch a new instance it will also open those files. But not if you do it from File -> New Instance.
