This came up in early November in the beta group--before 1.8 was released for the original Kobo but after the latest WiFi update was released. We were told that there was a bug in Kobo's implementation of the Adobe renderer. It was fixed in time to make it into the main code base, and thus into 1.8 for Kobo-1 and will be in a future WiFi edition. I have absolutely no idea when that might be happening.
We were also told that it goes to sleep from "home", but I haven't tried it to see.
PS: OK, now I have tried it and it does go to sleep the way it should from"home".
