One of the wonderful things about SL is that it gives us, visually anyway, that gift Robert Burns asked for... so when a friend recently IMed me that I was somewhat exposed, I was startled.
I double checked the edit I'd made to notecards controlling the items I wanted to be transparent. I commanded them to reset, which should have set them to their initial state, which the aforementioned edited notecards said should be transparent. Nonetheless, my friend could see them... and emailed me a photo as proof.
Other friends assured me I was observing the proprieties... and I trust that they tell me the truth, so what is different about the friend who IMed me? We compared client settings, and while I am far from thoroughly knowledgeable about that subject, we didn't see anything significant differing between us. My friend is investigating further on her own, as she has an item that to me looks proper, to her looks exposed. I am very curious about what is going on.
