I'd like to complain about this software...

Each one of these mini-incidents contains a small but useful piece of information information that is almost always lost. Most user problems don't generate any sort of report that is passed back to the developers; they are short-lived episodes that are not recorded anywhere. A 'report' could be a simple as a one-click 'I've just experienced a problem' button, or semi-structured text allowing users to say 'how can I put a UK phone number into this form which only accepts US formats?'
