Mystery of NonlinearFit

I have tried NonlinearFit in Mathematica 4 and found it gives satisfactory
results in some (few) cases and nonsatisfactory results in most cases.
What is the problem with it ?
Is there a bug report, specifying where it is worth trying, and where not ?
Some author (M.Kofler) says, it was working up to V2.2 and got corrupted
from V3.0 on.
Is there a way around other than the obvious : +ACI-Program it  yourself +ACEAIg-
