10.8.4 rmbp, 8gb. 2.6 So sometimes, not all the time, if I close the lid on my rmbp, and open it back up a few hours later it will take a few seconds to come up, I put in my password, then about 20 seconds later it will go back to sleep. Hit the space bar, and it will come back out of sleep again and let me put my password in a second time and work fine after. Not really the end of the world, but really weird issue. Anyone had anything similar or hints as to what I should do to resolve?
