I'm using a 23" ACD with my 2008 Mac Pro. I want to use the ACD's power button to "Sleep and wake the computer." I like it that way cause the small light turns off when the computer turns off. Which is fine, until I boot into Windows, which decides to change that. When I shut down Windows, I have to manually turn the monitor off. Then change the setting back in Mac OS X. Has anyone else experienced this or found a fix? I am currently using Vista Business 64 bit. It never did this with Vista HP 32 bit or Windows XP.
