function. It worked for me. I also removed the timer.reset();
timer.start(); from the sayPing() function. I'm not sure that you need
those.
This should help cure the 'tinnitus' :-)
Also - did you notice that you did not place the 'click' handler in the
button? It's in the TextArea component.
Others can weigh in on deleting an instance of a class ... I think that the
VM has a memory manager that takes care of that for you?

I've been working with Flex since last Februari, and since then I've been
having a problem with classes. Since it's seemed foolish that I could not
find the solution myself I've been hesitant to ask but here goes.
How do you delete and instance of a class?! I've set up a small example
with a class 'PingTime' which says 'ping' every second. And I'd like it to
stop, but not just stop but completely remove the class out of memory. How
do I do that? I'm sure there's a solution, and probably it's in the docs
somewhere, but I just can't find it.
How do I make the pinging stop?
Kind regards,
Sonja Duijvesteijn
