David, thanks for this advice which inspired another workaround:
After clicking the "Detect Displays" button (which will recognize the new screen and the loss of the old one) select "Apply" before configuring the new screen. Only after switching to a one-screen set-up, configure the new screen. This procedure will leave the configuration intact.
