Cannot resize our Adobe Premier application window in Windows 10 desktop

PROBLEM:  We cannot resize our Adobe Premier Application window on the desktop.  Is there a setting or preference that is forcing the application window to full screen?

BACKGROUND:  In Microsoft Windows, most program or application windows can be Full Screen, Resized, Minimized, or Closed using the buttons on the top right of the application's title bar.  In our case, we can use the all these buttons.  Nevertheless, when in the resize mode, the Adobe Premier application window is display in Full-Screen, but will not allow you to resize the application window.  We get the context arrow on the borders of the window, but when we drag it flashes, initially showing some of the desktop, but snaps back to full size when you release the mouse button.
