Oculus Utilities 1.39 breaks Rift touch controller Input for OVRInput.GetDown

Hi there, there seems to be a problem with Oculus Utilities 1.39

OVRInput.GetDown it never seems to work, but using OVRInput.Get works, so far.

However, as soon as I switched to using Oculus Utilities 1.38, OVRInput.GetDown would start working!

I'm guessing this not intended? I would love to see how we could rectify this, or if staying at 1.38 is the key...

Thanks
