The size of the display is not necessarily the issue - rather, it would be the display resolution. Right-click the Windows desktop and click Properties to bring up the display settings. See if you can increase the resolution used.
Thanks, But what if the resolution is maxed out? Its 1680x1050. its a 20 inch cinema display. Is there a keyboard shortcut or option to fit on screen? I cant drag the whole workspace up so for short, I cant resize the window since the lower right corner can not be adjusted.
