Optio L60 autofocus clicking

Any L60 users out there ? I've just purchased a refurbished [as new] L60 for my son to take with him to Australia next month. When taking a picture there is a continuous audible clicking as the autofocus adjusts. My daughter has an L40 and this noise is not apparent. The technical support guys say this is 'normal' but I've not encountered it before. Can anyone offer advice please.

Have just noticed similar posts [which I'd not found previously - Oooops] which have answered this question. Thank you.

Stick it in full auto mode, that seems to stop it 'clicking'.

It does on my E50 anyway!
