Dear Monks,
I guess this was probably questioned many times. But I did not find a working solution.
My code has computational overhead and I would like to inform the client that it should wait. The logic of my code is simple. After completing main_form() on the main page SUBMIT sends POST message. Then 
if ($submit)
{
        process_form(
...................

process_form() performs calculation based on recieved
$query->param(".....")
and then generates HTML whith computed results.
When computations are being performed main_form() is still shown.
I would like to show Wait .... message instead which will be interrupted when new HTML in iprocess_form() is generated.
There should be a simple solution. Your help is very much appreciated.
