Blaming and Practice

I've just started reading Elizabeth Taylor's last novel, Blaming, which was published posthumously. It's a good thing she didn't live to see the publisher's blurb on the back of the paperback, which begins 'While on holiday in Istanbul, tragedy strikes...' One can almost visualise Taylor, a fastidious stylist, wincing at the dangling participle - though it's the kind of thing we've now learnt to expect, in this age of semi-literate publishing. Something that makes me wince is the use of 'practice' as a verb. This often occurs throughout 'English' editions of American books - presumably as a result of a computer programme substituting 'practice' for 'practise' throughout, regardless of whether the word's being used as a verb or a noun. Whatever happened to copy editing?
