Sorry to be replying to my own threads, but this just gets more interesting.
Apparently, in IE and Firefox, the function must run to completion before
the UI is updated with any CSS / DOM changes, but in Opera, the UI is
updated immediately upon the jQ call.
I was trying to get a 'waiting' gif to appear at the beginning of a long
function call, but found that it was never appearing. I guess I need to
display the gif in a function before the long function.
