Just updated our WP installations to 2.7.
Generally, it looks very nice. But my wife has a big problem with it in that she uses an 800x600 screen res (her eyesight won't cope with a resolution any finer than that) and the text box for drafting a post gets squashed by the boxes in the right-hand bar.
Any easy fixes available? We'd far rather not roll back to 2.6.5!
