Does anyone that is using chameleon with the graphicsenabler flag set to yes have any problems with their computer not completely shutting down?

If I set it to NO then my laptop will power down correctly. All lights and fans will stop but with it set to YES I have to hold the power button down for several seconds to power off fully.

Any advice or suggestions greatly appreciated.
