Some windows don't fit on 1024x600, what can I do?
Unfortunately there are still plenty of pieces of software that do not take low resolution screens into account when designing their interfaces.
One workaround you can do when a window doesn't fit is to click and drag on any area of the window on it while holding the Alt key down, this will let you move the window up so that you can at least click the buttons on the bottom of windows.
As a fellow netbook user, I developed a "hack" or workaround (of sorts) for software like this.
It only works if you're running Unity 3D though.
So, hit the shortcut super + S to get the workspace switcher - you can now drag and drop the windows around as you please.
Example:
Despite the 11.10 in the screenshot, it does work in 11.04
