That iFly used the copy/paste function, not you guys. It's word for word identical in some places, if it was written independently there'd be more variance in language used. And the fact their manual, using the same language, contains the same mistake. In fact when I asked them about this very same issue, they didn't have the answer you gave - they blamed SE being 'unsupported' even though it clearly isn't a scripting issue or anything.
EDIT: Tried the find the PDF I'm referring to but it's long gone, I remember this clearly.
Thanks for confirming I wasn't making a mistake though, it is indeed hard to keep track of what's a Steam Edition only issue these days.
