The worst was when I discovered all console.log() crashed because IE6 left “console” as undefined until the developer tools were open.

Fortunately another bad feature of IE was to alert() the errors, so customers were aware of each of them and could easily send us the bug back...

This bank employee used PrintScreen to print the screenshot on paper. He the successfully faxed it to his email, zipped it and uploaded it to our bugtracker. I had the zip of a .tiff of a scan of a printed screen. I still wonder whether he did it because he was upset, or whether it was a usual workflow.
