The problem is not seeing the Stone properly, tether is doing that fine, and shows the same garbage as the Smoke Player.
This is from my client:
"Of note I did get Tether to work once. However, that was before discreet "fixed" antoher problem we where having. When we upgraded to Smoke 2007 we realized discreet had never tested switchable storage, Smoke 2007, and SGI. Therefore when we upgraded switching became very long. Discreet made a patch that made that process faster, however it seems to have had a negative effect on Tether."
