Nagging Formatting the document for copying popups

[ericwj]

Can you have a look at this please?

I'm fine disabling the extension, but I figure you might be interested to fix this performance issue which happily takes 10 seconds to copy half a line of text to the clipboard.

Also, even if you don't fix it, please just don't show the second message box after I kill it by clicking Cancel. I know the operation was aborted -- I clicked Cancel all out of free will.
