Window doesn't change when I click Restore symbol

Question: When I click the Restore button, my window doesn’t change. It’s still filling the screen.
Answer: This happened because while you were in the Restored view, you resized the window to fill the screen—instead of clicking on the Maximize button, which is what you should have done to make the window fill the screen.

To fix it, click the Restore button and resize the window back to the size and location you want (not filling the screen). Now every time you click Restore, the window will be restored to this new size and location—even if you close the window, and then open it again.
