Hmmm, prehaps a legacy of the fact that Mac mice (at least traditionally) had no wheels. I've thought about trying to finesse it but one problem is that the parameters controls don't appear to be standard Windows elements. The manual entry dialog you get by double clicking is a window so could probably popup a "wheelable" interface and use it to drive that but you wouldn't have the realtime feedback so it would be pretty useless. Maybe you could translate the wheel motion to drags. You might even be able to do that via the mouse driver setup. The Python method of course would work only if you have ProPack or Poser 5.
