Well Thats what I said, only, it didn't help. It was for a busy bar and the
bar would stop unless I was using the for loop with the time.sleep() in it.
However, it would always stop at the same spot with after(), but when I used
after(100, sleeper()) vs after(100, sleeper) the sleeper() would still stop,
but it would go a little further down the bar track. If that makes sense.
But I have given up on the idea for now, but thanks for your attempt to
help!
