Just got a new SE with a hard disk, and given all
the fuss about flickering screens on the net a while
ago, I looked very carefully at the the screen.  It
doesn't appear to flicker, but I noticed that the screen size
changes quite noticably (say, by 0.15") when the screen
image changes from very bright to very dark (by closing a window,
for example).

Is this a power supply problem?  Should I return it from the dealer
I bought it from while the warranty is still valid?  Or am I worrying
about nothing?  (It's a little way back to the place I bought it
from, so I'd rather  not return it until I have to.)

Thanks,
