If the windows are in the "restore down" configuration............not maximized and not minimized............they can be resized by placing the cursor at the edge of the window and "squeezing" the window toward whatever direction you wish.

Also, the entire window can be moved by placing the cursor in the blue band with the title............left click and drag the window around the screen.

You can then get one window on the left side of the screen............click on the second window and then do the same thing and move it to the right side of the screen.

It's a PITA and it takes a couple of minutes but you can get what you wish.

Caveat: This is with Windows XP..........presume that it will also work on Vista.
