SHARE, SUBST, and Windows in 386 enhanced mode don't get along.  Get rid of
one of them.  I had to get rid of SHARE, and am praying that nothing mucks
up my disk drive.

There was a long thread on SHARE, but it boils down to this:

SHARE protects you from having two processes write to the same file and 
destroy data.  It also (in DOS 4.0 and up) has the code to support > 32 MB
drives for programs that use FCB's (File Control Blocks), a DOS 2.0 and
earlier method for accessing files.  dBase III+ is an example of a program
that uses FCB's.

Let's put this SHARE explanation into the FAQ, ok?
