Many thanks for your concern. I've seriously thought about reversion to Snow Leopard. But my iMac came loaded with 10.7, already updated to 10.7.1. I think it's Apple's responsibility to make things work and to tell me precisely how to do them. Unfortunately, most tech support there has so far been wanting. I've got 90 days (now 78 days) to get them to give me what I need and make my set-up work.
I've always thought that most things in the world suck, and Apple is just confirming that in this arena.
