Gary, while I have seen spaced ellipses in printed work, I have seen what are likely proper ones just as much.

I think, for myself, one reason why certain publishers prefer spaced periods (though to me they often look like thin spaces have been inserted versus full spaces), is in many/most typefaces true ellipse characters are too compressed. They should have more space before/after and in between. In short, the should cause the text, and hence the reader, to "breathe." To let the reader to pause long enough to fill in the "blank."

Anyway, this issue has been around a long while.
