[Opensim-users] Diva Distro - Hitting Walls

Sat Nov 27 19:45:43 UTC 2010

An additional note.  While our UK guy is able to see the website, when he
opens the viewer and tries to get grid info in the grid manager, it does not
return the information; however when I try it from outside his network, I am
able to get the grid information in the viewer.  We all use the Imprudence
viewer.  Not sure if this bit of information is helpful.
