I recently upgraded my external display to the new samsung sa550 27" and I love the display, however, when my macbook goes into sleep mode the monitor does as well and the macbook thinks that the monitor is disconnected and places all my applications being displayed on the external back to my macbook upon wake. The first time it did this it only moved my mail program, now it moves everything. I know this is not normal operation because my other external monitor does not do this. Any suggestions? Thanks.
