Hi all,


I am having a really weird issues with my Mac Pro after I installed Mountain Lion. I have dual ACD Monitors.  Every time I reboot, the monitors switch sides.  In other words, the monitor that is in front of me with the dock would switch to the other monitor and vice versa after I reboot.  When I reboot again, it switches back again.  This is extremely annoying.  I have had to switch the inputs on the back of my computer every time.

Mac Pro, OS X Mountain Lion (10.8.2)
