I wish it was so!

I actually wasn't aware that SHARE was specifically needed in order
for the FCB calls to be correctly handled. I do have a program (Caxton's
Cardbox, a simple but very efficient and fast indexing/database program -
by the way it takes only 48k of memory which is one of the reasons I stick
with it) which does use FCB calls. I run it on a 386SX with a 132Mb hard
disk. All works fine until I try to run it from Windows, and then after some
time it will nearly alway crash with a DOS error message saying that there
are no available FCB's. This happens no matter to what number I set the
FCB handles in my config.sys, and how many of those I lock. A mistery to me.

Can somebody also tell me that if SHARE is automatically loaded if you
have a disk with a single partition > 32Mb, that if I specify to load SHARE
in my autoexec.bat I do no get a message saying that it is already loaded 
(which presumably it should have been), but if I load it twice in the
autoexec.bat or from the command line I do the second time get a message that
SHARE is already loaded. One more mistery.
