Hi Kirk,
PM is idle, just showing one contact sheet on the MBP monitor and one preview on the NEC Monitor.
Btw, discs are connected by FireWire, monitor is connected by DVI
Sleep-mode manually works fine until a photo has been edited.
After having edit a photo, it does not work by time and sometimes work manually.
I use Nikon CNX2 for editing for some years. CNX can handle sleep mode, if it runs solo.
