People love running programs on systems they weren't quite designed for, and NXT-G is no exception. Several people have found that it will run on very small laptops, but the screen size forces the configuration pane to be invisible, displayed off-screen. Problem.
TeamHassenplug has a solution.
Steve Hassenplug had this problem recently, and with some help wrote a wonderful LabVIEW tool that allows you to display the Configuration pane in a floating window - find it on the above page under "NXT-G add-ins". Now you can run NXT-G on screens with resolutions below N x 600, and have a nifty way to reposition information in the screen for taking screenshots, etc.
While you are there, you might want to check out some of the other tips, tools, and tidbits that pepper the site. There's a lot of information (and custom blocks) in the site.
And in the interest of full disclosure, yeah, some of the stuff on the site is mine as well :) .
