    My MBP sits closed in a Henge dock, connected to a external LED monitor

    Occasionally when I wake the MBP (via a BT Apple keyboard) the monitor will kick in but my desktop is not there (just a grey background no drives etc) and the Dock is not present, the Top tool bar is there but I have to apple>restart to get my desktop and dock back.

    Any ideas what might be happening/how to fix?

    I just unplug the mini display cable and that works too but why is it doing this? Mine is a 2012 MacBook Pro (Non Retina). What mine does is just moves everything slightly to the side, I can still see and use everything but is leaves a large black bar of unusable space to the far left side and it only happens sometimes.
