Let me guess: if you run your program from the DOS prompt, it works 
correctly, no matter how many times do you invoke it.  Right?

If so, this has something to do with reading console input from programs
run from within RHIDE.  The Ctrl-Z key (or the EOF indication it causes)
is not cleared, so the second invocation exits immediately. 

This problem pops up so rarely that it wasn't possible to debug it, 
AFAIK.  I also don't think it is really necessary, since it's not your 
program's fault anyway.

Run the program outside RHIDE, I'd say.
