Window too big for 1024x600 screen

I'm on a netbook with 1024x600 and the window doesn't fit on the screen. Horizontally I miss about 15mm. When I drag the window and snap on the right side, I see part of it end under Ubuntu's launcher bar. Vertically about the same. When I grab the title bar and drag it above Ubuntu's status bar, I can see the bottom (although there's nothing but white there). I can increase the size of the window by dragging the corners, but I cannot shrink it.
