Thanks for the idea, Peter-Paul - I'll try it out tomorrow.

Most browsers (except Opera) change the visible display of the page
only when all scripts have exited completely. Solution: use a timeout:

function show()
{
  gif.src = 'pleasewait.gif'; // or whatever
  setTimeout('slow_routine()',10);
}

Now the script exits after the gif has been set and the browsers show
it. Then the slow routine kicks in. Result: user sees Please Wait.
