Whenever I do a right mouse click on a list of sites and do a to open in new window, the window is 1/4 of the width of the screen. But when I do a left click on a list of sites it is normal and fills the screen. Where if anywhere do I go to set the new window so it comes up with a normal width and height.

The only time I've had to split my screen is if I want to see 2 windows explore screens when copying files from one dir to another. Thx in advance.
