I am having a problem with 286/386 WIndows.  I have a very simple program that
allocates ~ 2K of memory from the gloabal heap and keeps it locked throughout
the life of the program.  Runs fine on a 286 machine with expanded memory.
I have run SHAKER and HEAPWALKER and have not been able to produce any
bizarre behavior.

I then try running on a 386 COMPAQ with 3M of memory.  The program runs fine
and behaves correctly, but .......
When blipping the DOS window I get an error message that there is not enough
memory to display the directory.  An ABOUT shows the proper (close) amounts
of conventional and expanded memory.  Disc space is another issue.  I should
have ~20M free, but it shows 60M (it is a 40M drive).

What am I doing (not doing) to cause this ?

The Compaq uses caching (grabbing at straws).  Do I need to compile in
a special mode that allows 286/386 transportability ?
I am using MS C5.1 compiler and SDK.

Any help ?
