I've got an extra monitor hooked up to my powerbook, positiong directly above the powerbook. My dock and title bar are still on the powerbook screen. To use all the screen space, I want to drag some windows "above" the title bar onto the extra montior. But some apps don't let you do this - i.e. Safari, iCal, while others do, like iTunes. Does anyone know what the deal is with this? It's very annoying.
