My computer has suddenly gotten into the habit of displaying new windows as mere minimized postage stamps, instead of full screen windows.
What do I do to put it back?
Make the window the size you want, then close it. It should remember the last size.
Close all but one window. Stretch the window out to full screen size by dragging the corners. Hold down the Shift key, and click the red X in the upper right corner. Open a new window; it should be in the full screen size.
BING!
thanks.
