Triggering the Change event is the way Visual Basic does it too, and I have not
so fond memories of adding special code to avoid running the trigger every time I
set an index via the program's own code.

So how about we let you decide on a per list basis. Would a method to flag a
list as one that requires setIndex and setText to trigger an w32HChange event do?
I could even add into the parameter data to the event handler an indication
whether or not the event was operator or program initiated.
