Just started using DJGPP -- and love it so far -- but I have this one 
problem.  Full info follows:

This is a bug report for RHIDE Version 1.3  (Jun 10 1997 09:23:28)
I am running MS-DOS 6.22 (Windows 3.10)

Important environment variables:
PATH=C:\WINDOWS;C:\DOS;C:\BIN;C:\PERL\BIN;D:\DJGPP\BIN
DJGPP=D:\DJGPP\DJGPP.ENV
LFN=n
INFOPATH=d:/djgpp/info;d:/djgpp/gnu/emacs/info
LOCALEDIR=
LANGUAGE=
SHELL=
COMSPEC=C:\COMMAND.COM
DJSYSFLAGS=

My problem is the following:
============================

Any attempt to use interactive debugging in RHIDE (e.g., step or trace)
causes an "Unable to read from /dev/null" error dialog; when I click
'OK' for this dialog, perhaps a second passes, then RHIDE exits back
to DOS without warning.

Any thoughts on what might be up?
