home window can't be change size on fedora18

Question

I am running F18 64 bit on HP envy dv7 laptop. I can't fine the way to change the home window size it is always full screen. Occasionally come up to a standard half screen size, but then as soon as try to move it
around change to full screen. Is there way to correct it?

Answer 1

Click on the top border of the window, hold the click, and pull down.
The window should 'un-maximize'. Then you can resize the window as you
like, from the edges as usual.

For the reverse, you can double-click on the top border of the window.
Or you can click on top border of the window, hold the click, and push
it to top edge of screen. You may have done this inadvertently some
time, and it always opens at last used mode and position. :-)
