Thank you Cinnamon, indeed that's exactly this bug. I understand it's not due to the viewer version but to the operating system.
I'm gonna vote the jra, tho I'm afraid it's worthless as that funny Linden answers show in one hand, and because I don't know anyone willing to use that crappy SL 2.0 in the other.
Prolly better to post that request to Emerald dev.
Thank you a lot for your time Cinnamon
