 Hi, Ray, Paulo, and Stephen:

 It is XORG related. 

 Paulo:  Yes, you guessed correct. I was using xorgconfig and not xorgsetup.

 I [kind of] fixed part of the problem by editing xorg.conf and removing 
the "1280x1024"
in the 'Modes' lines.  Now, I can I have a confortable screen size 
without scrolling, but
only in 1024x768 mode.  800x600 modes has a virtual screen size of 
?1024x768? and
requires scrolling.  My monitor is a ViewSonic G773 and specifications 
indicate:
Fh 30-70 Hz
Fv 50-180 Hz
1280x1024 x 66 Hz
1024x 768  x 87 Hz
 800 x 600  x110 Hz

 My video card is nVidia GeForce IV (64MB).  I feel that this video card 
should easily
supply the above rates.

 I still have a larger virtual screen size than physical screen size 
when using modes
800x600 and 640x480.  :-|

Here is my /etc/X11/xorg.conf Screen and Server Layout sections:

# **********************************************************************

# Any number of screen sections may be present.  Each describes

    Device      "NVIDIA GeForce"
    Monitor     "My Monitor"
    DefaultDepth 24

# **********************************************************************

# Any number of ServerLayout sections may be present.  Each describes

Section "ServerLayout"

# The Identifier line must be present
    Identifier  "Simple Layout"

# Each Screen line specifies a Screen section name, and optionally

    Screen "Screen 1"

    InputDevice "Mouse1" "CorePointer"
    InputDevice "Keyboard1" "CoreKeyboard"
