Hi Jasom. I noticed when I tried copying an entire framework class, instead of just extending, that in addition to version, several other framework class references where required. I suppose that if you placed your copy in the same directory as the original, it would work the same. But, this isn't really practical. I gave up on that approach and concentrated on subclassing instead.
