I remember back in the day when we were adding more graphic channels to
Macromedia Director and we went from 64 to simply what the computer running our
implementation had the RAM and processor power to handle.
We set it higher (I forget what) but it was limited by the machine's
capabilities. That way we could up the max amount as machines gained
So, it might be able to support more, but not consistently across every
That's my guess.
