Not getting stabilizedTipPosition vector data on javascript PC

[james_pixel]

I'm developing a web app using javascript. I originally coded the app on a Mac, and was using stabalizedTipPosition data from the finger objects, however when I switched over to a PC the stabilizedTipPosition data is all 'undefined'. I checked in the leap-0.6.4.js file and found a reference to stabilizedTipPosition, but I'm not getting the vector data.
Wondering if there's something I'm missing.
Thanks!

What version of the core software are you running on the PC?

Hey Alex, thanks for the reply! I'm running Software version 4.0.0+52173.

stabilizedTipPosition is no longer present in V4, so you'll need to revert to an earlier software version.

Cool, thanks for letting me know.
