Good Afternoon. Running 10.6 on a MacBook Pro with the above build. I am still having the Caps Lock random reversal issue. I have a quick fix that does not require restarting the VM or Logging out. Switch to your vm In the Parallels Devices menu select your keyboard You will be warned that it won't be available to the Mac (go on, live dangerously) The Caps Lock light will come on. Press the Caps Lock key. Go back to Devices and deselect the Keyboard I hope this helps someone.
