hi guys, my axim x5 just came in the mail today. it looks great! i just have a few dumb questions...does the pda shut down? i mean, i press the button that turns it on and the screen goes blank, but is that shutting it down? and also um..when i open programs like games and excel and i close it by pressing the X on the corner...how come it's still open in the start menu...how do i close it? sorry for the dumb questions this is my first pda. :p
