Word 2002 open file question

Why does the Open file window (and Save file, Save As, etc.) always open in a full screen with no option available in the right upper corner to make the window smaller? Even if Word is running in a window which is not taking up the whole screen, the Open file, etc., command opens up into the whole screen. I have searched and searched but cannot find a way to make this screen smaller. Also, no double arrow is available to make the screen smaller. What have I missed?


Many thanks.

 

Thanks, Dave. Unfortunately, the pointer just doesn't catch hold of anything in the lower right corner of the pane. I tried but all that happened was that it picked up by taskbars on the bottom of the screen and rearranged them on the right side of the screen. The mouse pointer just doesn't seem to be able to latch onto anything along the edge of the "Open file" screen, which just fills the whole screen. Any other ideas?
