Small Screens

Hi Folks:
I have a quick question about my web site pages. When I am surfing around the net, pull up a web page, and click on a link in the page, the page does not come up full size like it used to. I do not think I did anything different and I can not figure it out. The pages open up about one quarter the size of my screen and I have to click the enlarge square at the top right of the screen for full size view. Any suggestions?

 

Open a window, maximize it, and hold down the control key while clicking the close button. This should make the windows open maximized all the time.
