Yeah, someone mentioned that behaviour a couple of days ago here in the forum. The IE/FF behaviour is saner, IMO, because making 100% sure that all JS/HTML elements are properly locked is, philosophically speaking, impossible, once one considers that arbitrary browser plugins and timer-triggered JS code can manipulate the DOM at literally any microsecond. > 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.

It blocks the user interface so the user cannot click on anything while your operation is running.
