Re: [BUG] running mc "over" running one

Hello, Jose!

Let's return the discussion to the list.  I've seen some complaints from
users reading the archives that the important pieces of the discussion are
missing when the discussion becomes private.

I think it may be a subshell problem, and there are good chances that it's
fixed in CVS.  At least is was fixed for Cygwin.  I have no idea why it
happens on your system.

Please try the latest snapshot from

There have been significant changes near this point in subshell.c

This means that the second mc has already created the pseudoterminal for
its subshell.  If it hangs, it happens quite late in the initialization
process, most likely in the subshell code.
