Hi, I am seriously getting fricking irritated and I would appreciate some help before I toss this computer out the fracking window. Every time I reboot, the stupid Mac Pro fails to recognize my main monitor, which is an Apple Cinema display, and dumps everything onto the second monitor. I can usually fix this by rebooting a couple of times or logging off and back on. Today nothing worked. So I unplugged my secondary monitor (a Dell) and rebooted, and things were fine...until I plugged the second monitor back in. When I did that it moved everything over to the second monitor, including the menu bar. So I turned the computer off and unplugged that monitor, and when I cut it back on I had the Apple Display fire up but with no menubar. So I swapped cable connections and tried again and the same thing occurred. Now, after 3 hours of screwing with this, I am stuck with with the tiny dell being the main monitor (with the menubar and desktop, etc) and the big Cinema Display as the secondary screen. I searched through the display preferences to see if I could make monitor one to be the main screen with the menu bar and desktop icons, but I see no such setting. All I can do is rearrange the displays and do color settings. BTW, I am using Snow Leopard now, but the same thing happened with Leopard, which is why I almost never update. I am using the latest SL, though. Please save my sanity.
