Not entirely sure if this is an 'Applications' or a Peripherals Q, but here goes...
I have a 23" Cinema display which I use as my sole display running off a 12" powerbook, which is usually closed.
When I set the resolution at the maximum (1920 x 1200) I can use the entire screen to view applications: true for Safari and Office apps such as Excel and Entourage. But I cannot make the window as large as I want in Word - the application window just refuses to expand beyond about 2/3 of the screen. Why is that?
