I have had a sofa for a while and has worked fine. After not using for a long time, I tried clicking it and it behaved like a decorative object, and would not work, not even the "touch" option appears. I checked its contents, the scripts are all there. I am no scripting expert so have no idea if somehow something inside has gone missing. I tired resetting the scripts, and added a reset script into the sofa, but didn't change. I tried the vendor, but I bought it so long ago they cannot help. Unfortunately the sofa is no copy, so there is no back up. Does anyone have any ideas how I can solve? Unfortunately Adam below was unable to help, the sofa seems as dead as a dodo. Does anyone else have any ideas? Following on from answers below, I did try rezzing the sofa at another sim, the problem persists. However, happily the vendor was able to send me a new copy, so I am OK now ... although would love to know what went wrong so I am going to carry on trying to see if I can find a remedy. Meanwhile thanks to everyone for the help ... I really appreciate it.
