Sorry for the long delay in getting to this.

I'm not sure if this has been fixed already, but when I try this with
simple programs I see the window reappearing every time and, as far as
I can tell, there should not be any race-conditions or anything like
that (at least I don't see anything suspicious in that direction).

So: maybe someone else already fixed this, or maybe I just don't have
a complicated enough program to see the problem. Don: if you have a
student's program where the test window doesn't appear (even 1 in 10
tries to see the bad behavior is okay with me at this point), that
would be useful to me.
