With my 10.5.8 iMac, I used to access it all the time from my laptop with screen sharing.
With my new 10.6.2 Core i7 iMac, it no longer works properly. If I share the screen from my laptop (it doesn't matter if it's a MBP 13" or an iBook 12"), I get both screens from my iMac shared, and it does work. However, it's impossible to navigate since it's two high def screens side-by-side, crammed in on a small laptop screen. However, if I tell screen sharing to only choose the main iMac's screen it will load that screen... and then hang.
I can see the content of the iMac's main screen, but I can't do anything with it. It's just a still picture. I can't exit screen sharing either without force quitting it.
With my previous iMac, switching to the main screen (or the secondary screen) always worked fine.
Anyone else encounter this problem? Any fix?
