Anyone having odd issues with their Thnderbolt display? Mine is working off and on, I sometimes have to switch power outlets for it to even come on, although all the pass through stuff firewire,network, usb etc stuff powers up and works fine I get no display. If I am in bootcamp and Windows dim's the display, if I reboot and let it go into Mac the display never comes back up either.. I've taken into Apple, and they replaced the main circuit board, power, and light sensor and I'm still having issues... I love the ability of the dock and all but for dropping a grand on this I shouldn't be having this kinds of issues. argghh..
