Does iChat screen sharing over the internet work in OS X Lion? If I upgrade to Lion, will I still be able to use iChat to take over my elderly father's Mac (we have MobileMe accounts) to help him with problems and software updates? I read in some forums that this is broken in Lion, but I don't know if those were isolated incidents or not. Kindly requesting that gracious Lion iChat users test this and report results here.
I also have the problem screensharing a Lion machine viewed on a Snow Leopard machine, but not the other way around. I stumbled on a fix. If you first start a video chat and then start screen sharing while the video chat is underway, it is able to connect. I was able to verify this several tries with it not working unless I first video chat.
