If you re running QPro in a VM like vDOSPlus under Windows, you can
can run Quickview in a separate window and switch between them because
both processes are running.

If you are running DOS, it's single tasking, so one app at a time.  As
mentioned, you would need to implement something like Quickview as a
TSR you could pop up over the running QPro session, or exit QPro and
then run Quickview to look at stuff.
