It's a nuisance if an application decides, on its own logic, to force you into multiple screens/instances. It's a feature if the user wants and asks for it. Agreed but this is not an adaptive problem at this point but a usability problem. An adaptive problem is a problem that a screen reader can not handle a usability problem is when a program does not work the way a user wants it to. If the program does not provide a choice then yep it is a usability problem. Solved very simply. Use another program if you do not like the features of the other program.
