This is the first problem I have experienced since switching to mac, and it is pretty terrible. Basically, after I put my mac to sleep, 90% of the time to use it again I have to restart it because of the problems after waking up. I posted a thread on the apple support forums, HERE. Is anyone else experiencing this? I am going to call apple tomorrow and see if they have an suggestions. If anyone else is experiencing this, please post about it. Anyone done anything that might fix it? Or do we have to wait until 10.5.n? When will there be a leopard update? thanks.
