So, I got the error message stated above and followed the advise given and changed hgrc line from monitors = get(0, 'MonitorPositions'); to monitors = get(0, 'ScreenSize');

now, when I try to plot, say a=1:10, plot(a,a) a gray figure appears but no data is plotted. The entire plot area is the default gray. It appears that the fix is not working universally. Using Matlab R2010a on a MacBook Pro OS X

Update, the problem appears to be in the position vector. The default provides large, negative values

Position = [0.130672 0.11 -233.083 -321.191]

That's a known result that can happen with multiple monitors.
set(0,'DefaultFigurePosition', [appropriate values])
can help.

Well, that seems cumbersome. There should be some basic fix. There are no multiple monitors in my set up. There is only the main screen. This error appeared spontaneously and from the number of mentions I see online, it is common.
