Tom, see upstream - it works fine for me now when I launch the polling
thread from the UI thread. I was launching it from the constructor of
another class, and for some reason this causes issues. It's quite
reproducible. If I launch the polling thread from the UI thread it
works. If I go back to launching it in the constructor it goes back
to being very unreliable.
I assume your example below is being called directly in the UI thread
as you are updating UI objects directly.
