Dell Inspiron 6400

My sweet new Dell has finally arrived, complete with Core2 Duo power (woohoo!). I did notice a weird problem when closing the lid, even temporarily. The windows would resize and reposition as if the screen size was changed to 800x600. I searched and searched and came up with this answer:

Fix: Close lid on laptop changes screen resolution
and
Annoying problem when close lid action set to "do nothing"

All is well now!
