A long long time ago, I was testing a web site. I accidentally suspended the server. Mozilla's progress bar stopped right there while internet explorer kept going, progressively slower, until the browser threw an error around 98%. Also, let's not forget windows file download/copy estimations. Lying progress bars are at least as old as windows.

The windows file copy process bar wasn't lying though, it gave you an honest estimate but was just really naive.
