Ever since I upgraded to 10.8.3 using the Combo update, whenever my computer wakes from sleep, I get an all-white screen.  I can "select" parts of the screen using the mouse and the regular wallpaper comes into view.  At that point I can use the computer just fine.  I have re-installed the combo updtae and restarted the computer but the "white-outs" keep happeneing.  Any thoughts as to why this is happening and what I can do to fix it?  Thanks.
