"Virtual Screen" help needed

[cashen@primenet.com (Dean Cashen)]

Hello:

This is my first post to this list, I subscribed as a new user
of a Thinkpad 760CD, still with only 8MB of RAM (and, as I'm
running Win95, my only suggestion about that RAM configuration
is DON'T DO IT!  Performance isn't, uh, "satisfactory")

However, my question is about the Virtual Screen capabilility.
On my now Win95-equipped Thinkpad, selecting the Display icon
in the "ThinkPad Features" program ("advanced" button) reveals
only greyed-out buttons to configure and select the Virtual Screen
capability.

What am I doing wrong?  The users manual alluded to selecting 
a driver for the virtual screen, but I'm unable to find where
I can choose that option.

Any help would be thankful,

Dean
