Say I am reviewing a software (or whatever), and after talking about its good features I get to list its drawbacks:
- Quite RAM consuming.
- Rarely crashes when various keys are pressed at the same time.
The word rarely sounds out of place, as if it were good that a bad thing, namely crashing, rarely happens. The point is that it should never happen.
Is my impression genuine? If yes, what is a proper replacement for rarely? Seldom and unfrequently seem to fail likewise. It must, of course, keep the meaning of something that happens at a very low frequency.
