I've been running 4dos on my 386/AMI BIOS/Chips & Tech
chipset/4Meg/VGA paradise 800x600 as the command shell, and I haven't
been having any problems. A friend of mine recently bought the same
hardware, and after she installed windows on her machine, I copied the
contents of my root directory onto her machine,  giving her
the same config.sys, autoexec.bat 4dos executables and startup files.

This resulted in 4dos being the command processor on her machine, and
worked just fine at the "Dos" level.  However, when I run 4dos on her
machine, the first 4dos window appears just fine. The second causes
windows to produce the message "This application has violated system
integrity and will be terminated.  Please close all applications, exit
windows and reboot your system."

As far as I can see, we have the *exact* same setup. I have no problem
running multiple copies of 4dos.

Another strange behavior on her machine is that if I run some dos
applications after the first 4dos shell, and before the second (no
obvious pattern/number required), the second shell comes up just
fine.At other times, this second shell will appear after some number
of intermediate dos applications are loaded, and will cause the
windows terminate message after I run a dos application in its window
and exit from the app. 

I was initially using ems swapping for 4dos (that is how it works on
my machine), but that doesn't work on her machine. I tried all the
other combinations too. I also switched to 600x400, and that didn't
help. 

If anyone has any ideas, or could pass this bug onto the developers of
4dos, I'd be grateful.

The only differences I can think of are:

-	She has a different disk controller and disk drive.
-	The disks that her windows came on are 5.4", mine are 3.5". (So I'm
	going to try and install win with my disks and see if that makes a
	difference.) 
-	The Bioses might have slightly different dates.


thanks,

kartik
