The basic telnet to the console is a generic facility shared by all simulators so 
if there is a problem in one it will be in all.

Well, before looking too closely for this, I tried with the latest source and it 
works as we expected.  The prebuilt Windows binaries are only generated 
when I feel like something useful has changed.  I was planning on generating 
new binaries later this week, but since this problem is fixed with the latest
code, I built and pushed out a revised set just now.   I'll leave finding 
exactly what was wrong (which has already been fixed) as an exercise for 
someone more interested than me.

As for addressing this problem.  Paul Koning provided me with a test case 
and the driver code which is raising the issue, but I haven't had time to dig 
into the specifics.
