I use two monitors alternately, a 27" Cinema Display at work, & a 24" Dell U2410 at home, running off my 2 yr old MB Pro, OS10.8.2. Both are 1920 x 1200 resolution. But the default window sizes are different within applications- when I switch from the Dell to the Apple, windows need resizing. Is there any way to make the defaults the same? I'm suspecting the OS is trying to compensate for the different monitor sizes. It identifies each monitor correctly.
