small window

[longshanks]

Morning I hope you can help anyone please. when I open my documents folder, it used to open full page .
now it opens as a line down the left side. I can put my curser on the line and get the double arrow, and draw it across the page how it used to be, but it wont stay that way. Have I clicked something I shouldn't' have.

anyone please.

Try holding down the shift key while resizing with the mouse.

Click on the box at the top right, between - and X. Once it goes to full screen close the window. Then try opening it again.
