I am having weird problems with my macbook, i think most are related to sleep. First, my macbook will come out of sleep for no apparent reason. Also sometimes after i intentionally awake from sleep, some things won't work. For example, when i move my cursor over the launcher on the bottom, the icons don't magnify. This has the same effect on the toolbars at the top. When I move my cursor over the different menus, they don't get highlighted. There have been a few times where the cursor is replaced with a rectangle of dots. A reboot fixes all these problems, but nothing else. Anyone know what the problem is?
