I'm just curious....
Sometimes the mirrors have updates with bad checksums and the update stays on for a few minutes until it figures out that somthing's wrong. I usually figure it uut a bit earlier, so I try to click the Cancel button. When I do, nothing happens. So, I wanted to know: does the button hav any purpose, or is it there just for people to click on it and be satisfied when it finall closes by itself?
Thanks
