I've been trying out previous versions (to find where the behaviour 
I've since re-installed 5.3.3 completely and it's behaving correctly 
now, so I assume it's something else that caused the problem.
Perhaps I should have done that before bothering the list here. Sorry.

Still it seems to be back to usual now.
