volume/panning doesn't work on Windows?

[mdtodd]

I'm on a private session with two other jammers. I'm on Windows and they are both on Macs. They can adjust other jammer's volume or pan them left/right, but my level controls for them don't change anything in my headphones (no volume change for individual jammers, no panning). We're all on the latest and greatest and have no other problems. Makes me wonder if there's a bug in the Windows version?

Thanks guys for a great product!
