tractordriver - the no flyouts is a good thing - it uses less of the screen, which is a plus...menus are more manageable.
It will take a bit of getting used to. If you remember windows 95, that used to have "fly out" menu's, but only 1 level...it used to scroll up and down when you had too many programs installed - the good old days
otester - closing explorer with your computer will not help with much performance - you've got enough memory to handle almost anything.
