Re: Behavior of References with Classes

Woops. I think I figured this out, but I tried to write a script to make sure I understood and (guess what) using references with the "new" operator is new to 4.0.4. ...and guess who only has Windows at home? heh heh O well. Anybody got a system running 4.0.4 that'd be willing to throw this script up there for me for a little ejamacation? I think it might be a good idea to recommend some serious editing for that section of the manual if what I think I've figured out is correct....
