it seems that the last in preference are the orders that come from the keyboard and the mouse. It should be the contrary. Is it really so dificult or it's a problem of filosophy?
generally when I order to stop clicking with the mouse on X or pressuring Esc in the keyboard, generally the computer doesn't obey mu order, and I cant roll the image.
I think the order of Stop must be accepted immediately. Is it so difficult to create a browser that respect the owner of the computer?
