when i put my imac into standby in windows, (which i wont do now anymore) i would bring it out of stand by, every other row of pixels was white and the other normal going up and down the screen, is this a boot camp issue? also extended display via the mini dvi port dosent work correctly in windows ethier, it just makes my screen 800x600 with not icons or taskbar and the ext monitor dosent even show display.
