Hi Nadya

I see no way to make the query continue if the user hits escape. To me the whole point is that the user is tired of waiting and wants to quit. If they hit escape by mistake, they'll have to learn to be more careful. You could put a window behind the progress bar, which advertises the escape key and warns of the consequences.
