YIKES!!!
I have had problems with SHARE on my 126Mbyte disk when running Windows 3.0.
So, I removed SHARE from my config, and have noticed no other problems.
But I am concered about this comment "living on borrowed time"!  It doesn't
seem to need SHARE to run fine, and with SHARE loaded, Windows has problems.
What gives?  Also, when my PC arrived from the manufacturer, SHARE was not
in the config - obviously they didn't seem to think it was needed.

Anyone have a definitive answer on this????
