Every now and then, maybe 1 out of 20-25 times, when I wake my MB Pro from sleep, the cursor and typing are sluggish, i.e., they don't keep up with my input at real-time. I've noticed that much of the time, it happens after the MB Pro is very slow to go from black sleep screen to login screen. In order to correct the problem, I have to restart the computer. I am on a 2.4 GHz MBP, 15 inch screen, OS 10.4.10, and running iTunes, Firefox, and rarely anything else when going in and out of sleep. Anyone have a solution?
