Had some problems myself with go32 and WinNT4.0 recently. 

I tried to run the <display> program which is compiled with djgpp v1.12m3.
I don't want to display anything but run some batch commands.
It works for a while and then gives up with memory problems.

Inspecting memory with go32-v2 gives garbage but obviously there *is*
only garbage left... because <display> cannot be started again to continue
with its work. I have to close the dos-box and reopen it to continue.

I'll test it tonight as Eli suggested (see above).

<display> seems to eat up all the dpmi memory and doesn't even free it
when it terminates (which is somewhat strange).

Sometimes WinNT pops up a message that the 
"System is running low on virtual memory"
(48MB RAM and 150MB of swap space, no other programs running)

I've tried several different versions of go32 without any change.

Unfortunetly I have no sources for <display>, the author seems to
have vanished and the original distribution site doesn't have his
directories any more. (And I'm not sure if the sources have ever been 
published at all.)

Questions:

1) Is there a problem with v1 programs and WinNT in general ?

2) Anyone out there who has access to the sources of <display> ?

3) Someone who has compiled <display> for DJGPP v2.x ?

4) Any hints, how to make the current setup work better ?
