Small glitches after wakeup from sleep

It's hard to find faults with my beloved MBP but there are some small glitches after the system is awake from sleep.
The top of my own list is that two-finger right-click stops working. Have to go to preference panel to reset it every time.

Tonight I have another one.. The trash bin sound disappears, while 'Play user interface' sound effect is still on. It is back to normal after restart.

Hope Apple will fix it in next update.
