Spellcheck again

One thing that the programs seem to regard as a feature, not a bug, is a very non-Aussie approach to hyphens. Even when in English (Aus) as a language the program will correct icecream to ice cream, titbits to tit-bits, and so on. I'm not sure whether their Australianisation is superficial, simply a matter of s's and z's, or whether they think this is the correct usage, even here.
