There should be no difference in the runtime files or how they work unless the DLL is not the same...

Check in your Windows directory and make sure there isn't a copy of wwipstuff.dll getting loaded from there instead of your local path.

But all of hte HTTP stuff doesn't use wwIPStuff, except for Formvar encoding if the string is long so I'm not sure...

Definitely sounds like a version issue to me.
