If I'm running PD8 while in dual screen mode and the OSX screen saver activates, OSX freezes up and I have to do a hard reset. This only happens while using the external monitor. I'm running ML on a 2012 rMBP. The external monitor is connected via the mini displayport to DVI adapter. I have already tried updating to the latest build 8.0.18314 rev 813278 Oct 31 Any ideas?
