Repetition is important because of two factors:
- Most people tolerate computers doing weird things. Restart the app or reboot are typical attempts to deal with things. Typical because it makes the problem appear to go away (reality is that it justs masks the problem).
- Most people don't want to bother IT with problems because the IT group may be unresponsive, they don't think the problem is important enough, or they just want to get back to work.
