Whenever I close my computer to put it to sleep and then open it up later, the computer freezes and I am unable to type in my password to unlock my computer and am forced to hold down the power button until it turns off and then reboot it. This has become a major pain and has only started today but has happened 3 times already. I have an Apple Bluetooth Keyboard and a Magic Mouse connected to my computer and am running 10.6.2 if that helps. Anybody have any idea as to what may be causing this and how I can fix it? I'd rather not have to shut down my computer all the time and I'm no longer covered by any protection.
