Help! Suddenly, while I can still rez a box OK in my favourite Sandbox, I can't open it. When I right-click and select Open it just sits there looking sullen. There's a glittery beam connecting it to my hand, but nothing else happens. Some boxes I can wear and open from their attached position, but not all. The only thing that works is to use the Second LIfe viewer and open there. I'm trying to think what I might have doen to precipitate the problem. I upgraded to 4.7.7 (48706) recently and I also deleted some temporary(?) files - can't remember why now, but, whatever, I've upset something. Everything else seems fine. Any suggestions would be received with total gratitude.
