I open Inventory tab. Then click + next to Notecards. All my existing notecards there have texture type indicator icons and cannot be opened to read nor edit. This condition is only on existing notecards, however. I can right ciick on Notecard, Create a new notecard, it appears named 'new note' and with proper notecard icon, can be edited and saved.
In SL this all works perfectly without error. This is only happening when I use Radegast to connect to Inworldz.
