Thank-you, Nya, for your response. I won't yell at you
/me points at the line where he mentions it works fine using Emerald Clones (i.e. Phoenix, Emergence, Emerald).
I also tried in different parcels/regions around the grid. I looked at the device settings, and they are set the same in SLv2 as they are in Phoenix.
So, not hardware, not network, not parcel/region. It is specific to SLv2.
