Velocity mapping

I am trying to limit the output velocity to a specific range (say 60-100) with an unlimited range of velocity input (0-127).
As soon as I enter any value apart from "-1" in the Second Data field (Velocity) in the mapping, Midi-Ox sends a NOTEON message when the actual note is RELEASED. i.e. if I play a note I get two "NoteOn" messages sent (one when the key is depressed and one when it is released).
I have tried everything I can think of to try and prevent this including specifically replicating the incoming NoteOff Message but to no avail.
Can anyone make any suggestions about this problem please ?
Or perhaps more simply, "What is the recommended method for limiting the range of output velocities ?"
Thanks,
Claire

The vast majority of modern MIDI equipment uses Note On Velocity Zero to indicate the end of a note.
For your input criteria, don't use 0 as the lower limit, use 1.

Deat Peter,
Thank you very much indeed. Your advice was perfect - Thanks !
I have now built a work around for my velocity map by treating Velocity '0' as a special case. i.e. I have had to use two lines of code. One which detects Velocity 0 and re-maps it to Velocity 0 (so it remains unchanged) and the next line which re-maps all velocities (which are not 0) to the desired range.
Thanks again.
Much appreciated !
Cheers,
Claire
