The above comment is wrong.

The "pass" statement is redundant.

It is hard to say as you are not posting the entire code.  As I
indicated above, you wrote a comment indicating that a given choice
was taking you out of the loop - which could only happen through a
break statement.  You may want to post a ("small") code sample that
can be run by itself and reproduces the problem behaviour you
observe.  The sample you posted include infinite loops with no way to
get out, so your original claim that you could leave the room and come
back is highly suspicious ;-)
