[development] animation with Ajax Module

[Don]

I'm using the Ajax module to submit a form in a block, Drupal 6.19.
It works fine, but there's no animation displayed to indicate that 
something has happened. The only feedback is the status message it gets 
back.
I've seen a clockface animation in some of the other forms, any way to 
get it to work here?
Any ideas before I strike out on my own?

Thanks.
